This is a direct-acting, 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 pilot at port 1 with sufficient pressure to overcome the spring bias and allow flow between port 4 and port 3, while port 2 is blocked. The spring chamber is vented to the atmosphere.

  • Spool valves will have normal leakage due to spool clearance.
  • Approximately 1 drop (0.07 cc) of fluid will pass from the pilot area to the vented spring chamber every 4000 cycles.
  • 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.
