This is a direct-acting, pilot-stage relief valve that can be used as a remote pilot pressure control device for other pilot-operated valves due to its pilot flow capacity is limited. The valve blocks flow from port 1 to port 2 until the pressure at port 1 is sufficient to overcome the valve setting, it lifts the poppet and opens the flow path from port 1 to port 2 (tank). Since the pilot flow is limited, this valve should be used with other main-stage or high-flow valves.

  • Excellent stability throughout flow range with fast response to dynamic pressure changes
  • Back pressure at port 2 (tank port) is added directly to the valve setting in a 1:1 ratio.
  • 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.
