Product Description

Normally Closed Diaphragm Valve without Coil - Body Only

When energized, the plunger is pulled to the top plug and opens a small "pilot port" in the center of the diaphragm plate. When de-energized, the solenoid plunger is pushed from the top plug by the kick-off spring and closes the pilot port. Fluid passes through the diaphragm bleed hole until pressure is equalized on both sides to shut off the large port.
