    Abstract: A normally closed electrically controlled valve (10) that utilizes two opposing pressures to solely control the movable valve member or plunger (28). The plunger (28) has substantially different surface areas at its extreme ends (28A) and (28G). The opposing pressures enter through the left inlet port (21) and the right inlet port (51) that are at extreme ends of the valve (10). The plunger (28) controls flow between the left inlet (21), a radial port (24) and an exhaust port (32). The magnetic coil (42) is positioned in such a way that when energized it attracts the magnetically responsive, freely rotatable ball (50) from its original seat (A) in the closed position to its other seat (B) closing off the right inlet (51). Simultaneously, this causes a pressure drop in the fight major chamber (27B) and consequently the pressure force acting on the major plunger end (28G) dissipates.
