At present, Taitong start-up globe valves include J641 pneumatic globe valve, J644 pneumatic angle globe valve, pneumatic water seal globe valve, and J661Y pneumatic high pressure globe valve.
J641 Pneumatic globe valveThe main purpose
The J641 pneumatic globe valve adopts a double-acting cylinder, which uses the upper chamber air intake or the lower chamber air intake to remotely control the valve, which is convenient and flexible to operate. Cylinder using medium: compressed air, nitrogen. Simple structure, convenient manufacturing and maintenance; small working stroke, short opening and closing time; sealing surface of closing body (valve) and valve seat are sealed by conical surface, with small closing force, erosion resistance and reliable sealing. The valve seat can be a replaceable valve seat, which can be combined with the material of the sealing surface of the closing part in any combination to meet the requirements of the working conditions and prolong the service life.
Structural characteristics of J641 pneumatic globe valve
1. Exquisite selection of materials, in line with relevant domestic and foreign standards, reasonable structure and beautiful appearance.
2. The valve disc and valve seat sealing surface are made of iron-based alloy surfacing or Stellite cobalt-based hard alloy surfacing, which has good wear resistance, high temperature resistance, corrosion resistance, scratch resistance and long service life. .
3. The valve stem is quenched and tempered and surface nitrided, which has good corrosion resistance and scratch resistance.
4. Various piping flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.
5. The valve body has a complete variety of materials, and the packing and gasket can be reasonably selected according to the actual working conditions or user requirements, and can be applied to various pressure, temperature and medium working conditions.
6. The inverted seal is made of threaded connection seal seat or body surfacing austenitic stainless steel, which is reliable in sealing. The replacement of packing can be carried out without stopping, which is convenient and quick, and does not affect the operation of the system.
Overview of J644 Pneumatic Angle Globe Valve
J644 pneumatic angle globe valve is a commonly used shut-off valve, which is mainly used to connect or cut off the medium in the pipeline, and is generally not used to adjust the flow. J644 pneumatic angle globe valve is suitable for a wide range of pressure and temperature, but is generally used for medium and small diameter pipes.
Features of J644 Pneumatic Angle Globe Valve
1. Compared with the gate valve, the structure of the globe valve is simpler, and the manufacture and maintenance are more convenient.
2. The sealing surface is not easy to be worn and scratched, the sealing performance is better, and the service life is longer.
3. When opening and closing, the valve flap travel is small, the opening and closing time is short, and the valve height is small.Overview
Pneumatic water seal globe valveOverview
Pneumatic water seal shut-off valve is suitable for the nominal pressure PN2.5~4.0MPa, the working temperature is 0~450℃ in the return water condensing system of the thermal power station and the system pipeline of the petroleum and chemical industry requiring isolation from the atmosphere, cutting off or connecting the pipeline in the pipeline. Medium, the applicable medium of Taitong pneumatic water seal globe valve are: water, oil, steam and non-corrosive gas.
Product Features of Pneumatic Water Seal Globe Valve
1. The selection of materials is exquisite, in line with relevant domestic and foreign standards, and the overall quality of materials is high.
2. The pairing of sealing pairs is advanced and reasonable, which improves the sealing performance and has a long service life.
3. The product is designed and manufactured according to the national standard GB/T12235, with novel structure and beautiful appearance. The connection end has flanges and welding, which can be matched according to different requirements of users.
4. The stuffing box is designed as a water-tight structure, and it is connected to the water packing of 0.6-1.6Ma, with low friction and good sealing, which can isolate the system from the atmosphere and ensure good air tightness. It is an environmentally friendly product.
5. The valve stem is quenched and tempered and surface nitrided, which has good corrosion resistance, scratch resistance and wear resistance.
6. Compact structure, flexible operation and convenient maintenance.
7. The inverted seal is made of stainless steel threaded connection seal or body surfacing of austenitic stainless steel. The replacement of packing can be carried out without stopping the machine, which is convenient and quick without affecting the operation of the system.
Overview of J661Y Pneumatic High Pressure Globe Valve
J661Y pneumatic high pressure globe valve is suitable for various systems of petroleum, chemical industry, hydraulic power and thermal power station with nominal pressure PN20～32MPa and P54/100V-P57/170V, working temperature ≤540℃ (P57/170V working temperature is 570℃). In the pipeline, cut off or connect the pipeline medium.
Features of J661Y Pneumatic High Pressure Globe Valve
1. The product is designed and manufactured according to ANSIB16.34 and E101 standards, and can be used with imported equipment.
2. The middle cavity of the valve adopts a pressure self-tightening sealing structure. The higher the inner cavity pressure, the better the sealing performance.
3. The sealing surfaces of the valve disc and valve seat are made of stellite cobalt-based hard alloy surfacing.
4. The depth of the bonnet stuffing box is reasonable, the packing is added with corrosion inhibitor, the sealing is reliable, and the switch is stable.
5. The valve has an upper sealing structure to ensure that the valve does not leak through the valve stem when it is opened and operated.
