This is a direct-operated, spool-type, 3-way 2-position, meter-in electro-proportional flow control valve. When de-energized, it allows port 2 to drain to port 3 (tank) while port 1 is blocked, flow capacity refer to performance curve. When energized, the current proportionally closes the spool to allow a metering orifice from port 1 to port 2. The valve self-compensates in this flow direction and provides additional pressure-compensated flow control when connected to an external compensator.

  • Please be aware that flow in the 2 to 3 direction is restricted to approximately 5 L/min (1 gpm).
  • The transition between positions is closed.
  • Continuous-duty rated coil.
  • Efficient wet-armature construction.
  • 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.
