The KDG4V333C30XMUHR760 valve belongs to the KDG Non-feedback Proportional Valves series and is produced by Vickers for electro-hydraulic automation where proportional spool control governs actuator speed and direction. This model uses solenoid-controlled actuation so an energized coil positions the spool in response to electrical commands, while a 24 V DC coil rating matches common machine power supplies. A spring-centered build returns the spool to neutral when power is removed, and a plain manual override lets maintenance staff shift the valve without electrical power. The unit tolerates system pressures up to 350 bar (5000 psi), and ports A and B pass up to 30 L/min for medium-flow circuits. It installs on an ISO 4401-03 / NFPA D03 / CETOP 3 (NG6) manifold, and its internal seals are compatible with antiwear hydraulic oils or non-alkyl-based phosphate esters.
Electrical termination is handled through an ISO 4400 (DIN 43650) plug connector, simplifying coil replacement and field wiring. There is no separate command input interface, so proportional output depends solely on coil current, and the design omits a feedback sensor, leaving spool position open-loop. The valve also contains no on-board electronics, allowing drive cards or PLC outputs to manage the solenoid externally. Reliable operation demands fluid cleanliness to ISO 17/15/12, limiting particulate wear in the precision metering edges. Physical dimensions of 237.998 mm in length, 48.260 mm in width, and 86.360 mm in height permit dense stacking inside compact hydraulic manifolds or subplates. Together, these attributes support straightforward installation and predictable performance within industrial motion control circuits.
