China High pressure industrial pneumatic regulator valve factory and manufacturers

High pressure industrial pneumatic regulator valve

Short Description:

Pneumatic low noise control valve uses modular design and impact structure. Through the special symmetric holes on the cntrol valve trim, Pneumatic low noise control valve could reduce the noise and pressure, thereby preventing from flashing and cavitation,make it applicable for high pressure difference and low noise conditions to meet customers requirements. caged seat and compressing connection of the valve body,greatly enhance the sealing grade and service life of the control valve , which make it easy to repair and greatly increase the general performance of Pneumatic low noise control valve.
Pneumatic low noise control valve pneumatic actuator makes the control valve realize the conversion of normal close and normal open on site easily,the spring of the control valve can be effectively protected from the corrosion to prolong the service life of actuator and convenient for customers operation. The actuator and the intelligent control valve positioner are connected pipeless to strengthen the antisemitic performance,stability and precision adjustment, to meet to exactly control of the working conditions.
