This is a pilot-operated, spool-type, 4-way 3-position directional valve. In center position, the valve allows cross flow between A, B and T, while P is blocked. When pilot pressure at port 5 rises to overcome the spring bias against the spool, the valve shifts to allow flow from P to B and from A to T. When pilot pressure at port 6 rises to overcome the spring bias against the spool, the valve shifts to allow flow from P to A and from B to T.

  • The minimum pilot pressure required to shift valve is 9 bar (130 psi).
  • Spool valves will have normal leakage due to spool clearance. 
  • All ports will accept 350 bar (5000 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.
