This is a pilot-operated, spool-type, 3-way 2-position directional valve. It allows flow between port 3 and port 2 with a spring-biased spool. The spool will shift when a pressure differential between port 1 and port 3 overcomes the spring bias and allow flow between port 2 and port 1, while port 3 is blocked.

  • When the pressure at port 1 exceeds the set pressure, a control-piloted flow (0.10 - 0.16 L/min) occurs.
  • 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.
