DG4VC32AMPS1H750

The DG4VC32AMPS1H750 valve belongs to the DG4 Directional Valves series produced by Vickers and is installed in hydraulic automation systems to shift flow paths under electrical command. It bolts to an ISO 4401-AB-03-4-A interface, so manifold and subplate layouts follow a widely used pattern for easy replacement. A spool coded as type 2 provides a closed-center neutral position that blocks flow and isolates pressure when the coil is not energized. Actuation is handled by a wet-armature solenoid, which submerges the armature in hydraulic fluid to damp vibration and extend service life. The coil is rated for 24 V DC and draws 30 W, setting the electrical load expected from the machine’s power supply. Reliable actuation is maintained down to 90 percent of the rated voltage, allowing operation during modest supply dips. When energized at 20 l/min and 175 bar, the spool reaches its commanded position in 60 ms, supporting intermediate cycle-time requirements. The hydraulic passage accommodates up to 40 l/min, defining the maximum pump flow that can be directed without excessive pressure loss.

Continuous operation is supported by a 100 percent duty cycle, so the coil may remain powered without mandatory cooling intervals. A 6.3 mm single-spade terminal provides the electrical connection, offering a quick slide-on interface for maintenance swaps. A water-resistant manual override lets technicians shift the spool during power loss while keeping moisture out of the mechanism. Port P, A, and B withstand 350 bar (5000 psi), enabling use in high-pressure work circuits, while the tank line tolerates 210 bar (3000 psi) on return paths. When power is removed under the same test conditions, the spool returns in 40 ms, limiting pressure spikes during shutdown. A spring arrangement marked A holds the spool in an offset position until magnet force pulls it to center, ensuring a known default state. The single-solenoid assembly weighs 1.6 kg, so one person can install or replace it without lifting equipment.
