ABSTRACT:
A fluid pressure control valve includes a double acting solenoid and a poppet valve seatable against two opposite valve seats. The respective solenoids are momentarily operated to move the poppet valve into respective valve seat positions. Solenoid actuation is terminated when the poppet valve reaches the valve seat position. The poppet valve is maintained against one of the valve seats by a spring force. A hydraulic force maintains the poppet valve against the opposite valve seat. One valve seat has a larger diameter than the other so that the hydraulic force against the poppet valve in one seat position develops a larger force than the spring force, whereas in the opposite valve seating position, the spring force is greater than the developed hydraulic force.
