DG4V32AMP7H750JA100

The DG4V32AMP7H750JA100 valve belongs to the DG4 Directional Valves series and is manufactured by Vickers for hydraulic automation systems that require electrically shifted spool control. A wet armature solenoid is used so hydraulic oil cools and lubricates the moving plunger, reducing mechanical wear during rapid cycling. The coil is encapsulated to Class F limits, and an internal insulation rating of Class H further increases thermal endurance when the assembly is mounted close to hot manifolds. A nominal coil voltage of 24 V DC enables direct connection to common machine power buses, while operation remains reliable down to 90 percent of that rating to accommodate voltage drops along wiring. Electrical load is fixed at 30 W, permitting straightforward sizing of power supplies and output drivers. Continuous service is supported by a 100 percent duty cycle, allowing the solenoid to remain energized without mandatory cooldown intervals and ensuring consistent spool positioning in closed-loop hydraulic circuits.

Its hydraulic and mechanical interfaces follow established standards to ease replacement. The CETOP 3 (NFPA D03) port layout makes the valve interchangeable with most sub-plates in the same size, and the ISO 4401-AB-03-4-A mounting pattern aligns the fixing bolts and seal grooves for leak-free installation. Working pressure at the pressure, A, and B ports is limited to 350 bar (5000 psi), giving the valve adequate capacity for medium-to-high pressure manifolds, while the tank port withstands 210 bar (3000 psi) so return line surges remain within safe limits. Total mass is 1.6 kg for the single-solenoid version, keeping manifold loading low and allowing one-person maintenance. An M20 × 1.5 female thread is provided on the wiring housing so standard metric cable glands or conduit adapters can secure the incoming power lead and maintain environmental sealing around the coil enclosure.
