The DG4V52BLJMUH620 valve belongs to the DG4 Directional Valves series and is manufactured by Vickers for hydraulic automation systems that require directional control of fluid flow. The unit uses a wet armature solenoid as its actuation method to shift the spool while maintaining oil-immersed damping. Its solenoid accepts a 24 VDC supply and draws 1.58 A, allowing stable magnetic force during switching. Electrical hookup is provided through a DIN 43650 (ISO 4400) connector, and the mating cable entry uses a Pg 11 thread to simplify installation in control cabinets. The internal spool is arranged in a spring-offset B pattern so the valve returns to its rest position when de-energized. A left-hand build layout is supplied, positioning the coil on the left side for installations that require mirrored port orientation.
The DG4V52BLJMUH620 withstands a maximum working pressure of 31.5 MPa, making it suitable for high-pressure circuits. Its T port can tolerate back pressure up to 15.7 MPa, preventing premature spool leakage when return lines are restricted. The mounting interface follows ISO 4401-AC-05-4-A so it fits standard CETOP 05 subplates without adaptation. Four M6 bolts with a thread depth of 14 mm secure the body, ensuring rigid clamping and alignment on the manifold. Mounting face flatness must not exceed 0.01 mm per 100 mm to avoid internal leakage paths. Surface roughness on the same face is held to 1.6 µm Ra to protect the seal between valve and subplate. Vickers design number 20 identifies the internal configuration and matches service parts across the series.
