Pneumatic Diaphragm Valve With Handwheel

Pneumatic Diaphragm Valve With Handwheel is an industrial control valve that combines pneumatic drive and manual control functions. It is mainly composed of a pneumatic actuator, handwheel mechanism, diaphragm assembly, and valve body.

Reliable sealing
A pneumatic Diaphragm Valve With a Handwheel adopts an EPDM+PTFE or EPDM+F46 composite diaphragm and forms a uniform pressure seal at the valve seat through a flexible fitting structure. Under the working pressure of 1.0 MPa, the leakage rate reaches more than 98%, which meets the requirements of a high-sealing system.

Excellent corrosion resistance
The valve body material of the Pneumatic Diaphragm Valve With Handwheel can be selected from UPVC, CPVC, PVDF, PPH, or CF8M stainless steel, which can withstand corrosive fluids with pH values ​​ranging from 1 to 14.

Safety
The handwheel of the Pneumatic Diaphragm Valve has a mechanical self-locking device, which can lock the valve position after manual opening and closing to prevent misoperation. In the absence of an air source, the opening and closing operation can be completed within 5 seconds, improving the system's safety redundancy and control efficiency.

Rapid control response
The built-in large-diameter cylinder and precision return spring structure enable the Pneumatic Diaphragm Valve With Handwheel to achieve rapid opening and closing in less than 1.2 seconds at a supply pressure of 0.4~0.8MPa, ensuring timely response under continuous or high-frequency working conditions.
