The DG4V32NHMU1B660EN38 valve belongs to the DG4 Directional Valves series and is manufactured by Vickers. It directs hydraulic flow to actuators in automated machinery where remote electrical control is required. The unit is solenoid operated, so an energized coil shifts the spool without mechanical linkage. Its coil accepts 110 VAC at 50 Hz or 120 VAC at 60 Hz, allowing use on common power grids. Continuous energization is possible because the duty cycle is rated at 100 % ED. Class F coil encapsulation guards the winding against moisture and vibration, while Class H insulation tolerates elevated temperatures that occur during long hold periods. Power demand remains moderate at 58 VA when the 60 Hz supply is applied, minimizing panel load. An ISO 4400 plug (DIN 43650) provides a standardized electrical connection for quick replacement. A waterproof manual override lets maintenance personnel shift the valve during power loss or commissioning.
The hydraulic circuit is managed by a two-position closed-center spool that blocks all ports when de-energized, preventing uncontrolled motion. A no-spring detented arrangement locks the spool in its last commanded position until the solenoid is energized again, eliminating the need for constant power to hold state. The valve tolerates system pressures up to 350 bar on ports P, A, and B, and it passes flow rates as high as 80 l/min to support medium-capacity actuators. An ISO 4401-03 (CETOP 3) mounting interface aligns with industry subplates, and the required mounting surface flatness of 0.013 mm ensures seal integrity. When fitted with the specified connector the enclosure achieves IP67 ingress protection, so temporary immersion or wash-down does not impair operation. Clean hydraulic oil to ISO 4406 cleanliness class 19/17/14 is necessary to avoid spool sticking and wear.
