This is a direct-acting, spool-type, 3-way 2-position directional valve. It allows flow from port 3 to port 2 with a spring-biased spool. The spool will shift when pilot at port 1 with sufficient pressure to overcome the spring bias and allow flow from port 3 to port 4, while port 2 is blocked. Ports 2, 3 and 4 are blocked during the transition.

  • The minimum pilot pressure required to shift valve is 10 bar (150 psi).
  • The pilot pressure required for full shift at rated flow is 20 bar (300 psi).
  • All ports will accept 350 bar (5000 psi).
  • The pressure at port 6 directly opposes port 1.
  • Spool valves will have normal leakage due to spool clearance.
  • 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.
