Product Details

Wholesale price of pneumatic thin film sleeve type pressure regulating valve

Due to its good stability, simple maintenance, and wide application, it can be designed as a balanced type to eliminate most of the static unbalanced forces on the valve disc, and has a certain damping effect, which can reduce the vibration caused by fluid flow. It can be used in situations with relatively large pressure differences and can be selectedMulti spring pneumatic membrane mechanismorElectric actuatorWait.

Control valve large allowable pressure differential injection:

1. The above is the standard configuration structure, with a metal to metal valve seat and a PTFE soft valve seat as an optional VI level seal. Hardened valve internals coated with Steller alloy can also be provided. We have more reasonable bolt and nut choices for specific usage temperatures.

2. PTFE V-ring valve stem packing is a standard configuration and flexible graphite can also be selected. An extended valve cover equipped with graphite packing can be used in situations where the temperature exceeds 232 ℃ (450 Fahrenheit).

3. The standard valve body materials are carbon steel and stainless steel, and various alloy materials can also be provided for highly corrosive applications.
