This is a direct-acting, spool-type, 2-way, 2-position proportional throttle valve. When pilot assist pressure is applied at port 1, it opens the flow path between ports 2 and 3, allowing metered flow proportional to the pressure at port 1. Pressure at port 1 is directly opposite to pressure at port 4.

  • Port 1 and port 4 should be limited to 35 bar (500 psi).
  • Working parts are heat-treated and high-precision ground to increase hardness for long life.
  • A variety of seal kit materials for different applications, see seals information under Technical Reference.
  • Winner's cartridges pressure rating tested to the standard of the NFPA specification T2.6.1 and the fatigue rating's assurance and verification level is "90/90".
  • WINNERcoat® Zinc-Nickel Plating is salt spray tested in accordance with DIN EN ISO 9227 for up to 1000 hours.
  • Winner guarantees that all products performance a 100% functional test before shipment.
