This is a pilot-operated, poppet-type (with minimal leakage), normally closed, non-pressure-compensated, electro-proportional throttle valve. In the de-energized position, this valve remains closed from port 1 to port 2. When current is applied to the coil, flow from port 1 to port 2 increases proportionally to the applied current. If you need precise flow proportional control (port 1 to port 2 or port 2 to port1), we recommend using with Winner's full series of compensators.
- Recommended PWM frequency: 60–150 Hz, application-dependent, with 140 Hz as typical.
- Typical hysteresis is less than 4% of the rated current at a 10-bar pressure drop (Pulse Width Modulated, PWM)
- Coils must be ordered separately.
- 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.
