ABSTRACT:
In a pilot operated fluid supply valve the usual control pressure applied to the control surface of a main supply valve can be interrupted by a fluid switch and replaced with a pressure which closes the main supply valve. The fluid switch is responsive to the load pressure in the load port of the main valve. The fluid switch may include a rocker arm actuated by a diaphragm in fluid communication with the load port. In one system, main supply and waste diaphragm valves are controlled by a pilot valve and a pressure reversing valve, and the fluid switch is positioned between one of those valves and the main supply valve. In another system, the main valves are controlled by a dual output pilot valve.
