This is for the ball valve to function efficiently, safely, and have a long service life. To guide you, here are the important factors that will help you select the right valve that will serve you for many years.

Valve Shutoff

This is a stopper that can only be rotated 90 degrees. It is commonly used to correctly regulate flow in industrial applications such as petrochemical and chemical, plumbing services, human workstations, and other critical machinery. It also serves as a safety element by ensuring that the flow is entirely stopped.

Swing Check

A swing check allows a ball valve to perform the same functions as a check valve. This prevents media flow from returning to the system.

Anti-static Device

An anti-static device prevents a buildup of static electricity due to valve friction. A static buildup is a fire hazard, particularly if the media flow is flammable.

Fire-safe Design

A backup metal seat for the ball valve is provided by a fire-safe design. This is especially important when the system temperature rises to dangerous levels, causing damage to the soft seat. The backup seat will offer support if the soft seat softens or melts, preventing leaking and an unintentional fire.

Standard Face-to-face Dimensions

These specifications meet ASME requirements, making it simple to change and replace the valve with valves from other manufacturers.

Indicators of Position

The direction of the flow is indicated by a position indicator. It is widely used in multi-port ball valves and sits on top of the ball. It’s also used to make sure a ball valve is properly aligned. To minimize damages and significant injuries in industrial processes, it is critical to be fully informed of valve operations.

Blow-out Proof Stem

A blow-out-proof stem contributes to safe and smooth industrial operations. It is an excellent addition that ensures the valve stem will not fly or blow out when the ball valve is receiving too much pressure.

Oil and Gas Industries

In the oil and gas industries, the pipelines used mostly need to be manually operated and should withstand critical service conditions. These will include extremely high pressures and temperatures or severely low pressures and cryogenic temperatures. These industries also include applications with high corrosion and erosion to which the ball valves must endure.
