The Diaphragm Valve is essentially a simple pinch clamp, closed by pressing a flexible diaphragm against transverse weir, when fully closed, the diaphragm seats against the weir providing a leak tight closure. The diaphragm valves are recommended for handling sticky and viscous fluids, slurries and highly corrosive and hazardous substances and other hard to handle mediums or where tight closure is prime factor. It is the most ideal valve to handle fluids that require high purity and should remain free from contamination. The Diaphragm Valve is a simple pinch type valve and of low pressure type because of large area of diaphragm and is extensively used for both On/Off and throttling services and finds its application in Waste & Water Treatment Plants, Filtration Plants, Chlorination Plants etc
It is a full bore straight through, give high flow performance with minimum turbulence, while giving 100% leak tight closure.
Perfect sealing and longer diaphragm life due to weir design
Valve is self cleaning with no pockets, recesses, corners, grooves or sharp edges in the direction of flow.
