China Pilot Operated Diaphragm Valve Suppliers

Pilot Operated Diaphragm Valve is a kind of indirect acting solenoid valves (also called servo operated or pilot operated) use the pressure differential of the medium over the valve inlet and outlet ports to open and close the valve. Therefore, they typically require a minimum pressure differential of around 0.5 bar.

The inlet and outlet ports are separated by a rubber diaphragm, also called membrane. The membrane has a small hole so that the medium can flow to the upper compartment from the inlet. For a normally closed indirect acting Solenoid Valve, the inlet pressure (above the membrane) and supporting spring above the membrane will ensure that the valve remains closed. The chamber above the membrane is connected by a small channel to the low-pressure port. This connection is blocked in the closed position by the plunger and valve seal. The diameter of this "pilot" orifice is larger than the diameter of the hole in the membrane. When the solenoid is energized, the pilot orifice is opened, which causes the pressure above the membrane to drop. Because of the pressure difference on both sides of the membrane, the membrane will be lifted and the medium can flow from inlet port to outlet port. A normally open valve has the same components, but works in the opposite way.
