Abstract

An inline solenoid operated fluid flow control valve includes a plunger housing and a plunger movable against a valve seat and pole piece within the flow line when the solenoid coil is energized. The plunger and plunger housing are axially coupled via a spring which absorbs impact when the plunger strikes the valve seat. A piston within the valve seat member provides a pressure balancing feature and the clearance around the piston provides for a minimum flow when the solenoid coil is energized, with full flow occurring when the solenoid coil is not energized.
