This is a pilot-stage, direct-acting, normally closed, double-lock, pneumatically-operated spool-type directional valve. When the external pilot pressure exceeds the spring pressure, the valve spool shifts to allow bidirectional flow.

  • The suggest inlet port is Port 2.
  • The minimum pilot pressure required to operate this valve is determined by the following formula: Pilot Pressure = 1.4 bar + (Pressure at Port 1 / 100). The pilot pressure range is therefore approximately 1.4 bar to 5 bar. For example, if the pressure at Port 1 is 210 bar, the pilot pressure is calculated as 1.4 + (210/100) = 3.5 bar.
  • The maximum leakage is approximately 0.7 cc/min at 350 bar (5000 psi).
  • All ports can withstand a maximum pressure of 350 bar (5000 psi), with the exception that the external pilot port can only withstand a maximum of 35 bar.
  • Winner offers various external pilot control port options. Please refer to Configuration Z.
  • 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.
