An improved pilot valve mechanism for controlling the flow of a pressure medium responsive to predetermined variations in a pressurized system. The pilot valve mechanism is constructed in such manner that a plurality of pilot valves may be connected in an assembly and may be operative to shut down operation of a flow system responsive to sensing of pressures that are above or below a predetermined range of operating pressure. Each of the valves may include a shuttle valve mechanism capable of interrupting fluid communication between the inlet and outlet ...
A quick bleeding pressure responsive pilot valve mechanism for rapidly bleeding a pilot controlled control pressure system responsive to sensing of an unsafe condition in a pressurized primary system, said pilot valve mechanism comprising: an elongated hollow intermediate body portion having a longitudinal extending central opening and internally threaded ends, said intermediate body portion having an inlet port, an outlet port and a vent port in communication with the longitudinal opening; a pair of externally threaded end sections in threaded engagemen...
