Abstract:
A remote actuated metering valve system for supplying water to a washing fixture includes a main metering valve and at least one remote actuating relief valve connected to the main valve by tubing. The main metering valve has an inlet and an outlet with a valve seat between them and a movable piston which when the valve is in the normal closed position has its front face seated on the valve seat and its elongated nose projecting through the valve seat. The piston is maintained in the closed position by supply line pressure which is transferred via a bypass timing circuit to a pressure chamber behind the piston where it is sensed by the rear face of the piston. The pressure chamber of the main valve is connected by tubing to a normally closed remote push button relief valve. A second length of tubing leads from the relief valve to the supply source at a point downstream of the valve seat. When the push button of the relief valve is depressed, the relief valve is opened allowing the pressure in the pressure chamber of the main valve to be reduced.
