The DG4V36CGMWB940S444 valve belongs to the DG4 Directional Valves series produced by Vickers and is used to route pressure and return lines in hydraulic automation circuits. A spool type 6 arrangement blocks the pressure port while connecting both work ports to tank, enabling a safe neutral position during standby. Its spring-centered configuration designated as “C” returns the spool to center when the solenoid is de-energized, so external centering hardware is not required. A wet armature solenoid design immerses the plunger in oil to damp noise and extend service life. Continuous operation is allowed because the duty cycle is specified at 100 % ED. Class F coil encapsulation dissipates heat, while a Class H winding insulates the conductor against elevated temperatures. The coil housing carries an IP67 rating to protect against dust and temporary immersion, and working ports p, a, and b can be pressurized to 350 bar without jeopardizing internal sealing.
The valve mounts to manifolds following the CETOP 3 / NFPA D03 pattern so it can replace other units that share this interface. Its ISO 4401-AB-03-4-A sub-plate footprint aligns the pressure and service ports accurately. Fastening is completed with M5-0.8 bolts, and a 4.00 mm locating pin hole prevents rotational misalignment during installation. To maintain gasket integrity, the mounting face must be flat within 0.013 mm and ground to a surface roughness no greater than 1.1 µm Ra. Electrical performance is preserved when the supply voltage remains at or above 90 % of the nominal rating, ensuring reliable actuation even under slight voltage drops.
