At LUCKY6S, you can rely on that we will make the high quality check valve manufacturers for your applications

LUCKY6S check valve manufacturers create check valves from the highest-quality materials. Check valves, also known as one-way valves, are designed to prevent backflow and safeguard compressors and pumps. Natural gas, mining, and municipal water are just a few of the industries and applications where they’re used.

A cover, body, seat ring, disk, and hinge pin are the essential components. They come in a variety of styles, including swing, lift, dual plate, and stop check valves.

The valve will be opened by the fluid pressure in the pipeline. Backflow will close the valve in the meanwhile. Check valves ensure smooth flow and automatically close as pressure drops.

LUCKY6S guarantees that your check valves will be manufactured and configured in the most efficient manner possible.

A one-way valve, clack valve, or non-return valve is another name for a check valve (NRV). It’s one of the most often utilized valves in a variety of industrial settings. A check valve’s principal function is to prevent flow from returning to the system (backflow).

The fundamental benefit of a check valve is that it is self-operating. A check valve will continue to work even if a plant or facility loses power. This valve’s mechanism protects other equipment on the upstream line from damage, pollution, and other potential issues.

Pipes, pumps, and other equipment may be destroyed if the check valve is not properly positioned. Fluids may also leak into places they shouldn’t. This could lead to contamination and compromise the process medium’s overall integrity.

The operation of a check valve is dependent on the flow of the process. The disc opens as the medium passes through the process line in the desired direction. Depending on the design of the valve, the disc of a check valve can be a flap or a ball. Meanwhile, the check valve closes immediately as the flow reverses or diminishes.

Injection lines, boilers, cooling towers, water and wastewater treatment facilities, washdown systems, and a variety of other industrial applications all need check valves.

LUCKY6S Supply The Different Types of Check Valves

Check Valves classified by Material

Bronze Check Valve

A bronze check valve is constructed of bronze, which is primarily composed of copper. Lead, zinc, and tin are also present. Aluminum, silicone, arsenic, phosphorus, and manganese are some of the other additives that can be employed. When these minerals are added to bronze, it becomes stronger than when copper is used alone. Furthermore, the bronze composition makes a check valve malleable, which means it will not break easily when bent.

A bronze check valve has high machinability, corrosion resistance, and wear resistance due to its increased strength. This type of check valve is commonly used in low and medium-pressure systems.

Ductile Iron Check Valve

A ductile iron check valve is built of a more sophisticated iron alloy including a particular amount of graphite. Ductile iron has a high ductility, meaning it does not easily shatter when flexed. It can withstand extreme heat and pressure.

A check valve composed of ductile iron is strong, durable, and has a high heat resistance. It’s also corrosion-resistant, yield-strengthening, and tensile-strengthening. A ductile iron check valve is costly, but it is sturdy, dependable, and can withstand demanding applications.

Cast Iron Check Valve

Cast iron, commonly known as gray iron, is used to make a cast iron check valve. This metal is made up of an iron, carbon, and silicone alloy. Remelting iron produces cast iron, which is generally mixed with scrap iron. There are, however, some occasions where it is blended with steel.

After the iron has been melted, it will be cast. The process of pouring molten iron into a mold is known as casting. As a result, the check valve’s shape is established. The mold will be given time to harden after casting iron.

The wear resistance and vibration damping of a cast iron check valve are excellent. It also has a good corrosion resistance. This type of check valve is extensively utilized in water lines, sewers, and utility systems in a range of industrial applications due to these features.

Cast Steel Check Valve

A check valve made of casting steel is known as a cast steel check valve. This process entails fabricating valve components from steel in its liquid state. The metal is heated and poured into the forms that have been prescribed. The metal is removed from the mold when the liquid has cooled and solidified. Shot blasting and grinding are used to remove the excess metal.

Casting steel has the advantage of being able to make check valves in a variety of sizes and shapes. This makes it an excellent choice for check valves that are produced in small quantities or have specific requirements.

Forged Steel Check Valve

A forged steel check valve is one that is made through the forging process. This procedure entails shaping billets while they are still solid after being heated. The billets are compressed using forging dies to achieve the desired shapes and dimensions.

The components of a check valve will have increased strength after forging. As a result, forged check valves are suited for high-pressure and high-temperature applications. These components’ grain structure has also been improved, in addition to their increased endurance. This contributes to the check valve’s overall robustness.

Another benefit of forging steel is that it produces check valves with thinner walls. This design helps to reduce the possibility of thermal fatigue during check valve operation. This also speeds up the cooling and heating of the check valve. As a result, this check valve is capable of handling the various pressures encountered in a system that cycles through phase-down and start-up procedures on a regular basis.

Stainless Steel Check Valve

A stainless steel check valve is a tough check valve that can endure a variety of circumstances in industrial settings. This sort of check valve is suitable for handling oil, gas, and water since it is made of stainless steel, which avoids the chance of sticking.

A stainless steel check valve is used to prevent backflow in corrosive and aggressive media flow because of its increased strength. It’s also employed in high-pressure and high-temperature environments.

A stainless steel check valve ensures no leakage in addition to its durability and corrosion resistance. This is an important feature since it prevents anything hazardous from escaping and injuring everyone who works with the system.

Brass Check Valve

A brass check valve is a check valve composed of brass, a robust zinc-copper alloy. Brass is an ideal choice for check valves in demanding applications due to its robustness. It has a good corrosion resistance and does not rust. As a result, it’s suited for a variety of flow qualities, including certain chemicals and fluids with significant corrosive properties.

Brass is also extremely ductile, making this check valve type ideal for use in extreme temperatures. In comparison to other materials, it is not easily broken. Because brass is easy to bend and shape, it’s a good choice for personalizing a check valve.

Check Valve classified by Media Type

Steam Check Valve

A steam check valve is a check valve that deals with steam and condensate in chemical and industrial operations. Steam is often used in industry to power various processes. However, it produces condensate, which must be removed from the steam line as soon as possible.

Water hammer and other major difficulties can result if condensate remains in the process line. Leaving condensate in the pipeline could create a pressure drop, which could result in flashing. The term “flashing” refers to the rapid evaporation of a liquid.

To manage steam and eliminate condensate, steam traps are put in the process system. Condensate will flow downstream after these goals are met. A steam check valve is used in this situation. It stops reverse flow in order to ensure that all condensate is evacuated. A steam check valve helps lessen flashing effects in addition to preventing reverse flow.

Gas Check Valve

A gas check valve is intended specifically for gas transmission services like compressor discharge. A reciprocating compressor is frequently used to efficiently move gas through pipelines across hundreds of miles. Only one direction of gas flow is allowed. When transferring gas, a gas check valve ensures that there is no reverse flow.

Pressure letdown, hydraulic lines, metering pumps, air lines, compressor inlet and outlet, and pump discharge are some of the various uses for a gas check valve.

Liquid Check Valve

A liquid check valve is a check valve that is designed to handle a variety of liquids. It works based on the velocity, density, and viscosity of the fluid, or a combination of these characteristics.

It’s crucial to remember that most valves are made to handle a variety of media. WOG will be stamped on a check valve, indicating that it can handle water, oil, and gas. If this is the case, the user must assess whether the check valve’s full build is suitable for the application.

Check Valve classified by Disc Design

Ball Check Valve

A ball check valve has a moveable ball that functions as the valve’s closing mechanism. Inside the check valve is a ball, sometimes known as a disc, that moves up and down to control the flow. The disc is designed to suit the valve seat. The conical form of the valve chamber aids in directing the disc into the seat for a tight seal.

A ball check valve is usually inexpensive and requires minimal maintenance because it is compact and simple. A durable material, such as forged steel or cast steel, is used to construct the valve body. This is to ensure that it continues to perform properly for a long period. Metal is the most common material for the ball, but other materials can be utilized depending on the need. The ball, for example, could be composed of polyurethane to withstand abrasive media.

This sort of check valve cleans itself. The ball’s spin avoids the possibility of particles becoming caught inside the valve seat. A ball check valve is commonly used in pump stations with low maintenance requirements.

Tilting Disc Check Valve

A tilting disc check valve, also known as a tilt check valve, is made out of a disc with a pivot point on the centerline. The disc opens to allow free flow in one direction and closes when flow is directed in the opposite direction, just like most check valves.

A tilting disc is a tiny and light piece of equipment. A tilting disc’s center of gravity is also very close to its pivot point. As a result, the cracking pressure of this check valve is minimal. The pressure at which fluid begins to leak before reaching the specified pressure is known as the cracking pressure. A set pressure is the point at which a pressure relief valve, or PRV, begins to open.

A tilting disc check valve is good for pump protection since it closes quickly. It’s commonly employed in liquid and gas handling applications.

Diaphragm Check Valve

A diaphragm check valve is a check valve with a flexible rubber diaphragm or a self-centering disc. Both of these serve as the valve’s closing mechanism. A diaphragm check valve works similarly to a standard check valve. It allows flow in one direction but prevents flow in the opposite direction.

Upstream pressure should be a certain amount higher than downstream pressure with this check valve type. The pressure differential that allows the check valve to open and allow flow is this amount. When the pressure is relieved, the diaphragm or disc immediately returns to its closed state.

A diaphragm check valve’s pressure differential can be set by the operator. As a result, this valve can be used in a wide range of applications.

Lift Check Valve / Globe Check Valve

Because it has a similar seat design to a standard globe valve, a lift check valve is often known as a globe check valve. It has a lift, which is either a ball or a piston, and a disc, which is also known as a lift.

Flow entering a lift check valve must always pass beneath the seat. The seat, which is guided by the upstream flow’s pressure, directs the ball or piston as it rises when the flow enters. When the flow reverses or stops, the ball or piston shuts as gravity and backflow drive it into the valve seat.

A lift check valve is well-suited to applications involving high-pressure, high-velocity flows. It is suitable for upstream flow in both vertical and horizontal pipes.

Chemical vapors, steam, air, water, and other flow constituents are all handled by this sort of check valve. Petrochemical, agriculture, food and beverage, chemical processing, water treatment, and medical applications are just a few of the industries that use it.

Swing Check Valve / Butterfly Check Valve

A swing check valve, sometimes known as a butterfly check valve, is a type of check valve that allows or prevents forward or reverse flow. It is constructed up of a moveable disc that controls media flow by swinging on a trunnion or hinge.

A cross-section opening in the seat can be at an angle or perpendicular to the center between the two holes or ports. Swing check valves are available in a variety of sizes. It is, however, usually larger than other check valves.

For gate valve applications, a swing check valve is commonly chosen. Because of the modest pressure drop via the check valve, this is the case. The body is offered in a straight or Y-pattern form. The hinge and disc are suspended from the valve body by a hinge pin in either case.

This sort of check valve has a metal seat-to-composition disc or a metal-to-metal type of seating. A composition disc is commonly employed in applications that demand a positive shut-off or when dealing with filthy fluids or other particles in the flow. It’s also utilized when there’s a lot of noise.

A swing check valve’s closing mechanism is based on reverse flow and the weight of the disc (gravity). The pivot point of this check valve is outside the disc’s perimeters. This indicates that when the pressure head is higher, there is a greater risk of reverse flow. The disc must travel at a 90-degree angle to the valve seat for the check valve to shut off fully.

Check Valves classified by Body Design

Wafer Check Valve / Dual-plate Check Valve

The body of a wafer check valve, also known as a dual-plate check valve, is composed of a durable thermoplastic with a wafer design. The valve’s function is performed by the body, which primarily consists of the seat and disc.

The disc is raised off the seat by the flow from one direction, allowing fluid to flow freely. Meanwhile, the disc is pushed back to the seat by the flow from the opposite direction. This provides a tight seal, which eliminates the possibility of backflow.

The compact design of a wafer check valve considerably decreases the likelihood of blockage. This makes it ideal for services that deal with huge amounts of materials and trash. It’s frequently employed in activities where fluid flow in a single direction is critical.

Chemical processing, tank inlets and outlets, power plants, bleach plants, mining, and water treatment plants are just a few of the applications where a wafer check valve excels.

Wye Check Valve / Y-Check Valve

The body construction of a wye check valve is similar to that of a Y-type globe valve. The stem and seat of the pipe are inclined at 45 degrees to the pipe’s axis. This check valve is utilized in high-pressure and high-temperature applications. It’s also employed in situations where pressure decrease isn’t a big concern.

It’s also known as a Y-check valve, and it’s commonly used in compressed air or liquid systems to allow single-direction flow. Freshwater, seawater, condensate, boiler feedwater, cargo oil, lubricating oil, fuel oil, combustible and non-flammable hydraulic fluid, and others all use it.

Angle Check Valve

When it comes to the outer features, an angle check valve is very similar to an angle type globe valve. An angle globe valve regulates fluid flow, but an angle check valve ensures that process media flows exclusively in one direction.

An angle check valve is constructed so that the axes of media flow entry and exit meet at a perpendicular angle. The horizontal line serves as the gateway for media flow, while the vertical line serves as the exit.

Slurry and other viscous fluids can easily pass through this check valve due to its shape. Furthermore, it protects the check valve from damage caused by flashing and fluid cavitation.

An angle check valve is commonly used in water and wastewater treatment facilities, the oil and gas industry, and the food and beverage industry because of these features.

Check Valves classified by End Connection

Flanged End Check Valve

The end connections of a flanged end check valve are flanges. When it comes to installing and uninstalling from a pipe, a flanged connection is the most convenient. Furthermore, it is the most typically utilized connection in valves, especially those that must be uninstalled and reinstalled frequently. To attach the check valve to the pipeline, the flanges can be clamped or bolted.

Compression Fitting Check Valve

End connectors with sockets are used to connect a compression fitting check valve to a pipe. A union nut is used to link the two pieces together. The connection is made by squeezing a sleeve or ring to the plain-end pipe’s exterior dimension. In steel and copper pipelines, a compression end check valve is commonly employed. It’s used in low-pressure applications or when the pipeline doesn’t have to be disassembled frequently.

Butt Weld Check Valve

A butt weld check valve has end connections that are bevelled to match the pipe’s machining bevel and wall thickness. The ends of a check valve are beveled before being butted to the pipe and welded. Because of its robustness, this connection type is often employed in steel check valves. It’s also employed in a check valve that doesn’t need to be dismantled all the time.

A butt weld check valve is suited for high-pressure and high-temperature applications due to its increased endurance. Oil and gas industries, water and wastewater treatment, petrochemicals, and other sectors employ butt weld check valves.

Threaded Check Valve

A check valve with threaded end connections is known as a threaded check valve. The check valve can be directly linked to the pipeline using male and female threads in this sort of connection. The installation is simple and does not necessitate any specific abilities.

A threaded check valve must, in general, have female threads. Male threads, on the other hand, can be utilized for certain applications. Tapered or parallel threads can be used. In a tiny bronze check valve, this form of end connection is frequently employed.

Threaded connections are commonly utilized in low-pressure and low-temperature applications because they provide excellent sealing. In operations with little to no vibrations, a threaded check valve is also used.

Socket Weld Check Valve

A check valve with socketed end connections is known as a socket weld check valve. When the check valve is made of steel, a socket weld is commonly applied. For high-pressure and high-temperature applications, this form of terminal connection is ideal. It’s also utilized in pipelines that don’t need to be disassembled frequently. Even when used frequently, a socket weld check valve ensures leak-proof sealing.

A socket weld connection is achieved by drilling the check valve’s ends with a socket. The interior diameter of the pipeline must be slightly larger than the external diameter. The pipe is put into the socket, butted against the shoulder, and a fillet weld is used to link it to the check valve.

In applications involving dangerous or combustible compounds, a socket weld check valve is frequently employed. Oil and gas industries, pulp and paper industries, and chemical and petrochemical industries are some of the industries that use a socket weld check valve.

Guide for Choose the Right Check Valves for Your Industrial Applications

Compressors, pumps, and other forms of equipment are all protected by check valves. This is why selecting the appropriate check valve for your application is critical. There are various aspects to consider before making a decision. This is to guarantee that you’ve picked the best choice possible.

Each check valve results in a loss of head. A decline in pressure head as a result of fluid viscosity and blockages in a process fluid is referred to as head loss. Pumps will consume more energy, thus it will be an additional cost. Choosing the right check valve design is a good method to cut down on head loss. The following are design elements that influence the extent of head loss:

The disc’s design
Body proportions
The interaction of the flow and the disc
The total area of the valve body that allows media to flow through it.
Disc A Check Valve’s Design
The disc’s location is a determining factor. If the disc is located within the process flow, head loss occurs. The employment of mechanical support, such as springs, to accomplish quick closure can improve the non-slamming qualities of a check valve. However, there will be a greater loss of heads. The disc is thrust into the flow with this configuration, causing turbulence.

A swing-type check valve is advised if head loss and slamming are a problem. Swing-type discs allow the disc to move with the flow rather than against it.

A Check Valve’s Body Design
Head loss is caused by a body design that causes turbulence. A check valve’s design must prohibit large changes in flow direction. This can be accomplished by having a body with a smooth contour. This creates a smooth channel for the process flow.

There are two things to consider when it comes to non-slamming features. To begin, establish how long it takes for a check valve to close. The manner in which the disc transitions from an open to a closed configuration is the next consideration.

Factors Affecting a Quick Closure


• Flow in the opposite direction or velocity
Allowing the reverse flow to close the check valve is not recommended in some situations. Because doing so may end in slamming. If surges and slams are a major worry, you must avoid this condition.

• Stroke length of the disc
This refers to the amount of time it takes for the disc to close. The check valve will close faster if the stroke is shorter.

• Assistive technology
A check valve can be made to close quickly by using levers, springs, and weights. Swing check valves have successfully blended various sorts of mechanical help in a variety of applications.

Factors Influencing Slow Closure
A check valve designed to close slowly permits reverse flow velocity to build up. To avoid surges and slamming, the speed at which a check valve closes can be measured and adjusted. Power actuators, oil accumulators, dashpots, and cushions are all options for controlling the speed of a slow-closing check valve.

Cost should always be considered when acquiring industrial valves. Some of the questions you might want to ask include:

“Does the initial price be reasonable?”
“Does the cost of energy use increase as a result of the loss of ahead?”

Low-head-loss check valves are normally more expensive. These valves, on the other hand, will eventually pay for themselves. Keep in mind that saving a little money on the initial purchase price may result in you spending more money in the long run. When purchasing check valves, the valve placement, parts, and labor prices, and system downtime are the most important aspects to consider.

When selecting a check valve, you must make some compromises. Each selection element must be weighed in its importance. This is to ensure that you make an informed selection and select the appropriate check valve for your needs.

Take the time to research different manufacturers once you’ve picked your decision. Examine their designs to determine which check valve is ideal for your requirements.

Check Valves classified by Application

Sanitary Check Valve

A sanitary check valve is designed primarily for use in the pharmaceutical industry. This check valve’s primary function is to prevent reverse flow and cross-contamination.

Depending on the use, this check valve may have a soft or metal seat. A metal seat is utilized for pure steam or condensate. Meanwhile, for high-purity liquid applications, a soft seat is used.

High-pressure Check Valve

A high-pressure check valve is made to withstand harsh circumstances in industrial settings. This sort of check valve can withstand extreme temperatures, as well as corrosive and aggressive media, in addition to high pressure.

A high-pressure check valve is commonly made of stainless steel. Other materials, however, may be utilized based on the system’s requirements. Forged steel, cast steel, carbon steel, cast iron, ductile iron, and other materials are among them.

The seat of a high-pressure check valve is also built of strong materials for positive sealing. Metal-to-metal seating, O-ring seating (Hydrogenated Nitrile Butadiene Rubber or HNBR is the usual material), and PTFE (Polytetrafluoroethylene) seating with a metal-to-metal seal are all possible seal solutions.

Hydrocarbon processing, natural gas facilities, chemical and petrochemical plants, wastewater treatment, and other industrial applications all use high-pressure check valves.

Vacuum Check Valve

A vacuum check valve controls vacuum levels in a venturi vacuum pump by establishing a tight seal. A vacuum check valve, like a regular check valve, permits air to flow in just one direction.

A switch closes the vacuum pump when it reaches the predetermined vacuum level, while the valve controls the vacuum level. Meanwhile, the pump will start automatically if the vacuum falls below the appropriate level.

A vacuum check valve with a cracking pressure of less than 1”Hg is suitable. As a result, the valve can keep a higher vacuum level.

Cryogenic Check Valve

A cryogenic check valve is made for cryogenic or extremely low temperatures like -196°C. This type of check valve can withstand temperatures well below zero degrees Fahrenheit. Stainless steel and copper are frequently used.

An extended bonnet is used on a cryogenic check valve to protect the stem. The length of the bonnet will be determined by the application’s parameters. To preserve optimum performance, this device keeps the stem packing away from the cryogenic fluid.

The creation of cryogenic fuels such as liquid oxygen and liquid hydrogen is commonly handled by a cryogenic check valve. Liquid helium and liquid nitrogen are two examples of liquefied gases where it is used.

High-temperature Check Valve

A high-temperature check valve is designed to withstand temperatures of up to 425 degrees Celsius. It can even withstand temperatures as low as 0oC. The temperature range is determined by the check valve’s overall design. Low, medium, and high pressures are normally handled by a high-temperature check valve.

This sort of check valve is composed of tough materials to withstand such temperatures. Stainless steel, cast steel, forged steel, and cast iron are just a few examples.

In important services such as condensate lines, process lines, thermal oil systems, and cold and hot water systems, a forged steel check valve is used. Process plants, steam plants, and boiler plants are some of the industries that use a high-temperature check valve.

What Are the Applications That Use a Check Valve?

Marine Industries

The marine industry relies heavily on industrial valves. Ships have grown in size and frequency of use over the years. As a result, ships must meet increasingly stringent criteria in order to operate at their best. Valves are essential in the production of power, control of HVAC, wastewater management, and many other areas.

Ships that store and transfer liquid cargo utilize check valves. They have to make sure that the liquid only flows in one direction at a time. This is to keep pollution and other issues at bay if the flow goes in any other way.

Check valves used in the marine industry must be more durable and dependable due to the scarcity of resources and the inability to obtain them once at sea.

Wastewater Treatment Plants

Wastewater treatment plants are facilities that deal with a wide range of industrial water treatment and pollution elimination procedures. Processes like this can be chemical, biological, or physical in nature.

Industrial wastewater disposal is a complex and expensive issue. Wastewater treatment facilities are on-site at the majority of chemical and petrochemical companies and refineries. This is to ensure that they are in compliance with all applicable local, state, and federal laws. The outcome is that enterprises such as these ensure the efficiency of their wastewater treatment facilities This is to keep you from having to pay for things you don’t have to.

Check valves are utilized for a variety of causes in these establishments. Check valves not only keep treated water from leaking back into the system, but they also guard against equipment damage from backflow. They also lessen the chance of contamination in several procedures as a result of using them. Check valves can also help reduce water hammer, which occurs when there is a sudden increase in pressure.

Food and Beverage Industries

Large companies like the food and beverage industry are still expanding today. As a result, the demand for sturdy and dependable check valves in these industries is expanding.

valves which have direct contact with materials and those which operate in utility services like water and steam have two types of check valves in these industries. There are specific standards for check valves that handle food products. A smooth check valve, for example, will prevent particles suspended in the valve from contaminating the product.

Check valves are rarely used in the food and beverage industry because of the high pressures and caustic substances that are found there.

Chemical Processing and Biopharm Industries

Check valves that can be sterilized are required in the chemical process and biopharma sectors. These businesses’ primary goal is to turn raw resources into finished goods. they have. Because of the frequent usage of high heat and pressure in these industries, the media that is utilized may be hazardous, abrasive, or corrosive. These kinds of flow should be tolerated by check valves with great tolerance. Backflow and cross-contamination can be prevented by using proper sealing techniques.

Oil and Gas Industries

In order to meet the growing demand for petroleum products, new technologies such as longer pipelines, deeper wells, and even lower production costs are being developed. Additionally, machines must be durable, perform better, and have a longer service life in addition to requiring low-cost industrial valves All of these things are required to keep up with the escalating demands of these sectors.

Strong and dependable check valves are required in addition to these specifications. These valves help to keep things running smoothly by controlling the flow of air. The integrity of the media flow can be compromised even if only a small amount of pollution is present. The expense to businesses will be prohibitive if this takes place. In addition, reducing pollution and backflow extends the valves’ useful lifespan.

It is essential that check valves used in the oil and gas industries have working conditions that can withstand high pressure, harsh temperatures and cryogenic temperatures.

Pipelines

Pipelines rely on check valves to keep the finished product safe. Thousand-mile pipes are used to transport media between the point of origin and the destination, where it will be altered and finalized.

Crude oil and natural gas are common media types in these pipes. Upstream and downstream lines, as well as midstream sections, all include check valves. This is to prevent contamination or backflow from affecting the quality of the flow media.

Pumps

Certain pumps also employ check valves. Ball check valves are commonly used in pumps with a diaphragm or piston drive, such as chromatography pumps or metering pumps. Check valves are used to prevent backflow in a variety of machines that use a similar mechanism to these pumps.

Industrial Processes

A variety of industrial processes need the use of check valves. Power facilities, chemical plants, and other industrial operations all use them extensively.

Check valves are commonly used in nuclear businesses for a variety of purposes, including dump lines, water control systems, N2 systems, make-up water, sampling and monitoring systems, and various process systems.

Whenever corrosive and aggressive fluids, high temperatures, and high vibration levels exist, check valves are utilized.

To make a single gas stream out of several different gases, check valves are used. Each gas stream has a check valve attached to keep the gases from mingling and contaminating the source. Check valves are fitted on both the oxidizer and the fuel sources, for example, if an oxidizer and fuel must be combined. Keeping the original gas containers pure and non-flammable is essential.
