This is a direct-acting, spool-type, 4-way 3-position meter-in proportional directional valve. In center position, ports A, B and T are allowed cross flow, while port P is blocked. When pilot pressure at port 1 rises to overcome the spring bias against the spool, the valve shifts to allow orifice flow from P to B, the flow is proportional to the pilot pressure (port 1). When pilot pressure at port 6 rises to overcome the spring bias against the spool, the valve shifts to allow orifice flow from P to A, the flow is proportional to the pilot pressure (port 6). Pilot pressures at ports 1 and 6 directly oppose each other.

  • The minimum pilot pressure required to shift valve is 4 - 9 bar (60 - 130 psi).
  • The pilot pressure required for full shift at rated flow is 20 - 23 bar (290 - 330 psi).
  • Normal operating pressures for ports 1 and 6 should not exceed 35 bar (500 psi).
  • 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.
