The KDG4V333C20NZMUH760 proportional valve is produced by Vickers as part of the KDG Non-feedback Proportional Valves series, and it serves to regulate flow and pressure in hydraulic automation systems that do not employ closed-loop feedback. An A-port flow capability of 20 l/min supports controlled medium-rate actuation, while a maximum operating pressure of 350 bar (5000 psi) allows operation in high-pressure circuits. The meter-in/meter-out configuration provides balanced flow control during both extension and retraction strokes. A spool arrangement that blocks port P and vents ports A and B to tank in the neutral position isolates the pump line when the valve is de-energized. Single-stage construction minimizes internal complexity and reduces shift time. Compatibility with the ISO 4401-03 (NFPA D03, CETOP 3, NG06) interface lets the unit mount on standard size-03 subplates. A tank port rating of 210 bar (3000 psi) safeguards return-line components from excessive back-pressure.
The electromagnetic section uses a 24 V DC coil so it can be wired directly to common industrial power supplies, and a resistance of 7.3 Ω determines the steady-state current drawn in service. Coil inductance of 20 mH influences dynamic response when the driver applies pulse-width modulation, while a maximum coil current of 1.6 A ensures full spool displacement without overheating. A continuous duty cycle rated at 100 % ED permits the coil to remain energized indefinitely during proportional control. Electrical hookup is completed through an ISO 4400 (DIN 43650) connector that allows quick field replacement. An ingress protection level of IP65 prevents dust and low-pressure water jets from entering the coil housing. Physical dimensions of 237.998 mm in length and 86.360 mm in height assist designers in allocating space within manifolds or machine frames.
