The dg4v32cmwb40s324 directional valve is produced by Vickers in the DG4 Directional Valves series for controlling actuator motion in hydraulic automation. It utilizes a closed center spool so all ports are blocked in neutral, isolating downstream lines during standby. Actuation is provided by a wet armature solenoid that minimizes noise and avoids external contamination, and each coil draws 30 W of direct-current power to keep electrical load low in machine panels. A spring centered arrangement automatically repositions the spool to center once power is removed. The spool shifts within 60 ms when energized and returns within 40 ms when de-energized, delivering predictable timing for control algorithms. The valve accommodates up to 40 l/min (10.5 US gpm) of hydraulic oil and withstands 350 bar (5000 psi) on pressure and work ports, supporting high-pressure mid-flow systems.
The body mounts to an ISO 4401-AB-03-4-A CETOP 3 pattern, simplifying interchange with standard subplates, and correct installation requires a surface flatness of 0.013 mm to keep internal leakage low. An IP67 rating shields the solenoid assembly from dust ingress and brief immersion, allowing placement on outdoor equipment. The coil is specified for continuous duty at 100 % ED, permitting uninterrupted actuation cycles, while Class H insulation endures high winding temperatures to maintain reliability under steady energization. Acceptable system oil cleanliness is ISO 19/17/14, so typical return-line filtration is adequate. The tank port may see backpressure up to 210 bar (3000 psi), enabling use in circuits with counterbalance valves, and the double-solenoid unit weighs 2.2 kg, permitting installation without lifting aids.
