The KDG4V334C15NZMKUP6G760EN102 valve is part of the KDG Non-feedback Proportional Valves series manufactured by Vickers for hydraulic automation tasks that require precise spool positioning without integral feedback. Its spring-centered build returns the spool to neutral when power is removed, keeping circuits at rest. An ISO 4401-03 (NFPA D03, CETOP 3) mounting interface allows direct stacking on standard subplates. The unit tolerates inlet pressures up to 350 bar, while the tank line can withstand 210 bar, setting safe limits for return flow. A nominal flow rating of 15 L/min defines the volume it can pass at rated conditions, and the meter-in/meter-out arrangement lets designers control both the supply and exhaust sides of an actuator. An IP65 enclosure resists dust and low-pressure water jets so the valve can be used near washdown zones, and a mass of 2.4 kg permits straightforward handling during installation.
The solenoid operates on a 12 VDC supply; a coil resistance of 1.55 Ω at 20 °C governs steady-state current, and a 4 mH inductance at 1000 Hz affects response time during PWM drive. Allowed current peaks at 3.5 A when the ambient temperature reaches 50 °C, which defines the required capacity of the power amplifier. A flying lead Deutsch connector provides a sealed electrical junction suitable for mobile or industrial machinery. Because no feedback sensor is incorporated, position must be inferred from the command signal. The design also omits a manual override, preventing manual spool shifts during maintenance. A relative duty factor of 100% ED means the coil can remain energized continuously without exceeding its thermal limits.
