Patent ID: 10598194

Abstract:
A fluid valve assembly for controlling a single-acting or double-acting actuator comprises a valve body having a central bore with at least one supply port for receiving a supply of fluid under pressure, at least one actuator port (C1,C2) for providing a control fluid pressure to an actuator, and at least one exhaust port (EX1,EX2). At least one pair of counter-acting metering edges operationally tied together by a stem movable within central bore in an axial direction a pilot force. Each metering edge of each counter-acting pair comprises a mating seat surface (PS1,PS2,PS3,PS4) on the valve body or the stem, and a poppet ring (PR1,PR2, PR3,PR4) supported by a flexible element (SD1,SD2,SD3,SD4) to the valve body or the stem in a manner allowing a relative axial movement of the poppet ring and the supporting valve body or stem also in a closed state of the respective metering edge.
