Electric Control Valve
High Pressure Industrial Pneumatic Regulator Valve

High pressure industrial pneumatic regulator valve

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.

FAQ

What are your prices?

Our prices are subject to change depending on supply and other market factors. We will send you an updated price list after your company contact us for further information.

Do you have a minimum order quantity?

Yes, we require all international orders to have an ongoing minimum order quantity. If you are looking to resell but in much smaller quantities, we recommend you check out our website

Can you supply the relevant documentation?

Yes, we can provide most documentation including Certificates of Analysis / Conformance; Insurance; Origin, and other export documents where required.

What is the average lead time?

For samples, the lead time is about 7 days. For mass production, the lead time is 20-30 days after receiving the deposit payment. The lead times become effective when (1) we have received your deposit, and (2) we have your final approval for your products.
