Diaphragm Valves

Diaphragm valve, which controls flow by a movement of a diaphragm. Upstream pressure, downstream pressure, or an external source (e.g., pneumatic, hydraulic, etc.) can be used to change the position of the diaphragm.

Diaphragm valves are suitable for handling sticky and viscous fluids, slurries and highly corrosive and hazardous substances. It could be used for handling air, water and  normal liquid/gas flow as well. It is the most ideal valve to handle  fluids that require high purity and  should remain free from contamination.
