This valve is a direct-acting, spool type, pressure-compensated, normally closed bi-directional flow control. It controls flow in both directions, allowing regulate flow from port 2 to port 3 or from port 3 to port 2. Port 1 is used for pressure balancing the spool and armature and must be blocked in all cases that operating pressure does not affect the operating characteristics of the valve. Bi-directional flow is pressure-compensated. The regulated flow is proportional to current applied to the solenoid.

  • If you require a higher maximum operating pressure, a factory-set minimum flow (port 3), or additional flow options, please contact the Winner sales department.
  • Note: Coil must be ordered separately. Use 12V DC or 24V DC (Series EC-23C) coils only.
  • The maximum leakage is approximately 0.3 LPM.
  • Continuous-duty rated coil.
  • Efficient wet-armature construction.
  • 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.
