This is a pilot-operated, spool-type, standard balanced proportional relief valve. The regulated pressure is proportional to the input electrical current. It blocks flow from port 1 to port 2 until sufficient pressure is applied to port 1 to open the pilot section by offsetting the electrically induced solenoid force. Pressure at port 2 is added to the cracking pressure. Applying current to the coil increases the induced spring force, thereby increasing the valve setting.

  • The maximum leakage at reseat is approximately 30 cc/min at 70 bar (1000 psi).
  • Reseat pressure exceeds 85% of cracking pressure.
  • Dither frequency should be adjustable between 80 – 300 Hz (recommended frequency: 85 – 300 Hz).
  • Customer must specify a relief setting (configuration Y). Please contact us if pressure control beyond the specified range is required.
  • Continuous-duty rated coil.
  • Efficient wet-armature construction.
  • 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.
