ABSTRACT:
A solenoid actuated valve of an in-line construction having an inlet and outlet between which are located the valve's operating components including a piston with a hollow head which engages a seat for sealing the valve's main flow path. The piston head has a discharging orifice which is sealed by the pilot pin of a solenoid operated popper and a charging orifice through which high pressure fluid from the valve inlet is supplied. The poppet has flow passages downstream of the piston seat which communicate with the valve outlet. In a normally closed type valve, the solenoid is energized to move the poppet and withdraw its pilot pin from the piston head's discharging orifice and the high pressure inlet fluid admitted to the piston head interior through its charging orifice discharges through its now open discharge orifice at a faster rate than the fluid entering through the charging orifice to create a low pressure condition on the seating area of the piston and permit it to travel away from the seat and open the valve's flow path. In a normally open valve configuration, both the piston and poppet are biased away from seating and flow path sealing portions so that when the solenoid is operated the poppet is moved to a position where its pilot pin seals the piston discharging orifice and the fluid flow pressures within the valve body changes to move the piston to a flow path sealing position. The valve may also incorporate a dynamic flow limiter located at the valve's inlet to limit the fluid flow available to be supplied to the interior of the piston head.
