This is a direct-acting, spool type, 4-way 3-position solenoid valve. When both coils are de-energized, port 1, port 2 and port 4 are open to each other while port 3 is blocked. When S1 is energized, it allows flow from port 2 to port 1 and from port 3 to port 4. When S2 is energized, it allows flow from port 3 to port 2 and from port 4 to port 1. During transition, all ports are temporarily interconnected with restricted (orifice) flow.

  • Continuous-duty rated coil.
  • Efficient wet-armature construction.
  • Spool valves will have normal leakage due to spool clearance. For low leakage applications, please contact the Winner sales department.
  • 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.
The performance curves of ES-31A-4C-24-Z-04 show pressure drop as flow increases. The operating limit curves indicate that for flow between Ports 3 to 2, Ports 3 to 4, Ports 4 to 1 and Ports 2 to 1, operating pressure corresponding to flow direction

The performance curve or data is only for reference, as customers' using condition, pressure, flow, hydraulic fluid viscosity, cleanliness, temperature and so on are different, the curve or data will be different.
