ABSTRACT:
A solenoid operated valve, including a balanced operating position when the valve is closed, is disclosed for use for handling pressurized air. The valve includes a valve body having an interior portion with at least one valve seat selectably contacted by a valve seal. The valve seal is mounted upon a longitudinally extending valve stem which is connected at one end to a diaphragm and at the other end slideably connected within the valve body itself. The diaphragm separates an interior portion of the valve into an inlet chamber and an expansion chamber. The valve seat separates the inlet chamber from an outlet chamber, the inlet chamber in communication with the air supply and the outlet chamber in communication with the air destination. The area of the valve seat is of equal area to the diaphragm. The outlet chamber and the expansion chamber are in air communication. When the valve seal is closed against the valve seat, the inlet chamber pressure acts on the valve seal and the diaphragm, which results in balanced forces resulting from their respective equal areas. The outlet pressure acts on the valve seal but is balanced by equal force in the opposite direction acting on the diaphragm. The valve can be modified to a three-way valve with an exhaust portion by including a second valve seat and providing air communication between the expansion chamber and atmospheric pressure.
