The DG4V50AMUH620 directional valve belongs to the DG4 Directional Valves series and is manufactured by Vickers for hydraulic automation circuits. It uses solenoid-operated actuation so an electrical signal shifts the spool without manual leverage. The coil is rated for 24 VDC, allowing direct interface with common industrial control voltages, while power consumption of 38 W defines the load that must be supplied by the control cabinet. A standard ISO 4400 (DIN 43650) connector simplifies wiring and ensures sealed mating with the coil. When maintenance personnel need to jog the valve, a plain manual override provides local movement of the spool. The unit is intended for subplate or manifold mounting, and its interface conforms to ISO 4401-05 (NFPA D05) to match industry-standard port patterns. A spring offset end-to-end arrangement returns the spool to its default position once coil power is removed, supporting fail-safe operation.
The valve supports system pressures up to 315 bar (4500 psi), permitting use in high-pressure circuits, and the tank port is limited to 160 bar (2400 psi) so reservoir plumbing can be sized appropriately. It accommodates flow rates to 120 L/min (32.0 gpm), giving headroom for medium-capacity actuators. Compatible petroleum oils must meet a cleanliness level of 19/17/14 to limit wear on the spool and body. Acceptable fluid temperatures range from −20 °C to 70 °C, enabling operation in cold starts and warm running conditions. These limits, together with the specified cleanliness rating, ensure dependable service life when the valve is installed in automated machinery.
