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

  • The maximum pressure at port 3 is recommended to be limited to 210 bar (3000 psi). For any technical questions, please feel free to consult the Winner sales department.
  • The pressure at port 4 is directly added to the valve setting.
  • 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.
