This is an anti-shock, pilot-operated, balanced poppet, ventable relief valve. The valves regulate the maximum system pressure and control the rate at which the pressure increases. They open and then close gradually at a constant speed, unaffected by the settings or flow conditions. The valve includes a vent port (port 3) that connects the main piston to the pilot stage, allowing remote control in pump unloading application by other pilot valves, 2-way valves, proportional relief valves (PRB8A) and other valves. With the pressure adjustment screw, both the maximum relief setting and the minimum limit setting are controlled.

  • This valve features a balanced poppet design to reduce cavitation and manifold erosion during high pressure drop applications.
  • Note: If your application is used in high pressure and low flow, please contact the Winner’s sales department.
  • Back pressure at port 2 is added directly to the valve setting in a 1:1 ratio.
  • This valve is not proper to use in load holding applications due to spool leakage.
  • 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.
