The KFDG4V52C70NZMU1H720 valve is produced by Vickers and belongs to the Directional Control Valves series for hydraulic automation. It shifts spool positions with a solenoid-controlled actuation system, providing electrically commanded flow direction without mechanical linkage. A spring-centered build returns the spool to its neutral state when the coil is de-energized, ensuring fail-safe centering in standby conditions. The 24 V DC coil voltage matches common mobile and industrial power supplies and keeps control wiring uncomplicated. An integrated feedback sensor reports spool position for closed-loop accuracy during proportional control tasks. The unit supports a maximum pressure of 315 bar (4500 psi) so it can be installed in high-pressure circuits. Port flow for the A and B work ports reaches 70 L/min, allowing medium-capacity actuators to move at required speeds. The ISO 4401-05 (NFPA D05/CETOP 5) mounting interface lets the valve bolt directly onto standardized subplates in manifold assemblies.
An ISO 4400 electrical connector with a fitted plug provides quick disconnection for maintenance while maintaining enclosure integrity. The design omits a manual override, removing hand-actuated bypass that could disturb automated sequences. Internal metering follows a meter-in / meter-out pattern to balance cylinder flow during extension and retraction. The valve operates without on-board electronics, so an external drive card must generate the proportional current for the solenoid. Compatible fluids include antiwear hydraulic oil and non-alkyl phosphate esters, giving flexibility in fire-resistant or conventional systems. A cleanliness level of 17/15/12 limits particulate contamination that could score spool lands. Physical dimensions are 335.026 mm in length, 70.104 mm in width, and 106.172 mm in height, permitting installation in compact power units or machine frames without exceeding standard cabinet depths.
