KFDG4V52C70NZMUH720

The KFDG4V52C70NZMUH720 valve is produced by Vickers for the Directional Control Valves series and regulates directional flow in hydraulic automation circuits. Actuation is provided by an electrically driven solenoid so a controller can shift the spool on demand. A spring-centered build returns the spool to neutral when power is removed, establishing a fail-safe stop position. Hydraulic passages handle 70 L/min through the A and B ports, allowing the unit to serve medium-flow machinery. Internal components withstand 315 bar, supporting high-pressure systems without derating. Meter-in and meter-out metering lets designers trim acceleration and deceleration rates, and the 24 V DC coil interfaces directly with common low-voltage control rails.

The integrated feedback sensor reports spool position to the machine controller, enabling closed-loop proportional control of actuator speed. There is no manual override, so every shift command must originate from the electrical circuit. Acceptable media include AW hydraulic oils and non-alkyl phosphate esters, offering compatibility with widely used fluids. System oil must not exceed ISO 4406 cleanliness class 17/15/12 to protect the lapped spool surfaces from wear. Closed-loop monitoring combines with strict cleanliness to maintain repeatable response during continuous service. These features make the valve suitable for automated presses, material-handling lines, and other installations that depend on precise, electrically modulated hydraulic control.
