This is a direct-acting, poppet type, 2-way 2-position, normally closed directional valve with an external drain. It blocks flow between port 3 and port 2 with a spring-biased spool. The spool will shift when there is sufficient pilot pressure at port 1 to overcome the spring bias, allowing flow from port 2 to port 3.

  • 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.
