Abstract: A proportional solenoid-controlled fluid valve assembly having a fluid pressure balancing arrangement includes a poppet and diaphragm. The valve assembly also includes a solenoid coil assembly having a cylindrical conduit and a magnetic orifice piece positioned within the conduit. A plunger is positioned within the conduit and is movable within the conduit between a de-actuated position and an actuated position. A valve poppet is provided having a top cylindrical upstanding portion and a poppet face configured to abut the valve seat. Further, a diaphragm is positioned within the valve base with the top cylindrical upstanding portion of the poppet extending through a diaphragm opening.

Abstract: A valve assembly includes a valve base having a tubular section with a longitudinal bore formed therein, a fluid inlet port and a common port with an internal passageway therebetween. A solenoid coil is adapted to generate a magnetic flux and includes a longitudinal axis and a bore coaxial therewith. The valve assembly further includes an orifice piece positioned within the longitudinal bore of the valve base. The orifice piece includes a central passageway with a first end and a second end. A plunger is movable within the longitudinal bore between a first de-actuated position and a second actuated position.
