ABSTRACT:
An improved solenoid actuated, fluid control valve includes a diaphragm which is fluid actuated. Inlet pressure through a restricted orifice into a chamber on one side of the diaphragm acts against the diaphragm and causes closure of the valve, when the solenoid actuated valve in the passage from the chamber to exhaust is operated. When the solenoid or pilot operated exhaust is actuated, then the chamber is depressurized and the fluid flow valve opens.
