G Series Diaphragm Valve
Product Overview
Patented Technology
The structure is simple, safe and durable, and the performance is stable. The diaphragm valve is one of the best choice when involving the turn off or control operation of abrasive or corrosive slurry, powder or particles.

Diaphragm valve is a special form of cut-off valve, the opening and closing part is a diaphragm made of soft material, which separates the inner cavity of the valve body from the inner cavity of the valve cover. No metal parts directly contacting with the slurry thus prevent corrosion and pollution to slurry. It also has stable performance and long service life.


• It can realize bubble level sealing. The no direct contact between metal parts and slurry ensures absolute zero downstream leakage; 

• Bi-directional full-pass runoff to decrease pressure drop, reduce wear and prolong service life; 

• Automatic cleaning structure design to avoid solid particles stuck or block the valve, thus ensure the stable sealing performance; 

• Modular diaphragm designed to facilitate the user to replace it. 


It is applied to the control on transportation of slurry with acid-base corrosion in electric power and environmental protection industry.
