ABSTRACT:
An improved valve includes an inlet, an outlet and a valve seat. A flexible diaphragm assembly seals against the valve seat. A bleed assembly extends into a pressure chamber located above the diaphragm for bleeding fluid pressure out of the chamber, thereby opening the valve. The bleed assembly includes a hollow tube inserted into a plastic plunger seat that is carried on the cap of the valve beneath the plunger of an actuating solenoid. Such a bleed assembly does not need a bleed tube having a precisely controlled length, and is not sensitive to flexure of the cap.
