This is a direct-acting, spool-type, 3-way 2-position directional valve. It allows flow from port 3 to port 4 with a spring-biased spool while port 2 is blocked. The spool will shift when a pressure differential between vent port (port 1) and port 3 overcomes the spring bias, allowing flow from port 3 to port 2, while port 4 is blocked.

  • 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.
