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. A magnetic frame is also included for securing the valve assembly in an assembled configuration, wherein a magnetic path is formed by magnetic orifice piece, plunger and the magnetic frame and the solenoid coil is configured to be actuated such that the plunger moves towards the magnetic orifice piece, thus lifting the poppet and allowing pressurized media to pass from the inlet port to the outlet port.

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 pressure balancing diaphragm is provided having a top side, a bottom side, an outer annular flange portion, a U-shaped portion, and an inner annular flange terminating at a diaphragm opening, with the diaphragm being positioned within valve base with the outer annular flange portion abutting the ledge of the valve base and the U-shaped portion abutting the valve seat. A retainer is also provided having a top cylindrical upstanding portion extending through the diaphragm opening and an aperture formed in the plunger. A magnetic frame is also included for securing the valve assembly in an assembled configuration, wherein a magnetic path is formed by magnetic orifice piece, plunger and the magnetic frame and the solenoid coil is configured to be actuated such that the plunger moves towards the magnetic orifice piece, thus lifting the diaphragm and retainer and allowing pressurized media to pass from the inlet port to the outlet port.

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.
