This is a pilot-operated, spool type, normally closed electro-proportional throttle valve. It designed for applications requiring essentially zero leakage blocking and load-holding. This valve is similar to check valve when energized. Allow free flow from port 1 to port 2 and block flow from port 2 to port 1. In de-energized condition, this valve is allowed flow from port 2 to port 1 but it is difficult to pass that flow from port 1 to port 2.

  • Coils must be ordered separately.
  • Continuous-duty rated coil.
  • Efficient wet-armature construction.
  • Working parts are heat-treated and high-precision ground to increase hardness for long life and essentially zero leakage.
  • 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.
