Abstract
Pressure regulating mechanically operable valves intended primarily for use as pressure regulating shut off valves are disclosed. The valves utilize a simple piston assembly operative between a valve open position and a valve closed position responsive to a spring biasing the assembly toward the open position against an opposite force proportional to the outlet pressure. The piston assembly may have only a single seal to seal the assembly against leakage with a mechanical shut off mechanism operative on only a 180 degree rotation thereof being cooperatively disposed with respect to the piston assembly so as to not require any additional seals. An electrically operable unlatching means is provided to close the valve upon receipt of a pulse from a battery or other electrical system, exemplary circuits, including a unique moisture sensing system are enclosed.
