Diaphragm Check Valves and Floating Disc

Diaphragm Check Valves and Floating Disc

These types check valves are almost always normally closed. Diaphragm Check Valve types rely upon a formed elastomer shape sealing against a surface in the flow path with enough stiction to overcome any backflow pressure that may exist in the system. The membrane shifts within the housing as the forward pressure increases until it is greater than the backflow pressure. When this differential occurs the diaphragm either compresses or bends to allow the valve to open and the media to flow around the diaphragm and out through the outlet.
