Diaphragm Valves

Threaded & flanged weir type valves

Diaphragm valves stop the flow of liquid by pushing down a flexible diaphragm into the passageway. Weir type diaphragm valves are most popular, as the diaphragm rests on a weir rather than the bottom of the valve passageway which limits the stretching and wear of the diaphragm. 

As the diaphragm, which can be made of a wide range of materials, isolates the valve’s moving parts from the liquid flow, diaphragm gate valves are popular options for aggressive fluids and those containing solids, as the valve’s moving parts can still be made of inexpensive materials.
