The DG4V32CWB12 valve belongs to the DG4 Directional Valves series manufactured by Vickers for hydraulic automation where precise flow control is required. The unit is driven by a wet armature solenoid that accepts 12 V DC, and the coil consumes 30 W so panel designers can size power supplies accurately. Continuous operation is permitted because the duty cycle is rated at 100 % ED, while a minimum supply of 90 % of the rated voltage prevents sluggish actuation during low-battery conditions. Thermal durability is supported by Class F encapsulation and a Class H insulation system, both of which guard the winding against overheating in confined manifolds. Internally, a closed-center spool blocks ports in the neutral position, and a spring-centered arrangement returns the spool to this state automatically when the coil is de-energized. Connection to manifolds follows the ISO 4401-AB-03-4-A interface so the valve fits standard CETOP 03 cavities without adapters.
The hydraulic envelope handles pressures up to 350 bar (5000 psi) on ports P, A, and B, allowing the valve to sit directly on high-pressure pump lines. Energizing the coil shifts the spool in 60 ms, and de-energizing releases it in 40 ms, timings that help system designers predict actuator motion. Mounting screws thread into M5-0.8 (10-24 UNC) holes, and reliable sealing depends on a mounting surface held flat within 0.013 mm and finished to 1.1 µm Ra, values that limit oil bypass across the gasket. These mechanical tolerances, together with the pressure rating and response times, confirm that the DG4V32CWB12 can serve as a repeatable directional element in compact hydraulic manifolds.
