The DG4V36CMU1B73EU38 valve is a solenoid-operated unit manufactured by Vickers within the DG4 Directional Valves series. It directs hydraulic flow in automated machinery and returns to neutral through the spring-centered arrangement coded C, so the spool recenters when the coils are de-energized. The internal 6C spool blocks port P while connecting ports A and B to T in the center position, allowing actuators to depressurize during standby. Working ports P, A, and B tolerate 350 bar (5000 psi), and the tank port is limited to 210 bar (3000 psi), supporting high-pressure systems. The coil is encapsulated to Class F and insulated to Class H, enabling reliable performance at elevated temperatures, and it is rated for a continuous 100 percent duty cycle so stops for cooling are unnecessary. Electrical connection is provided through an ISO 4400 (DIN 43650) plug, giving a standardized interface for field wiring.
Environmental and installation data round out the specification. With the ISO 4400 plug fitted, the enclosure achieves IP67, protecting the electrics against dust and temporary immersion. The valve requires system fluid no dirtier than ISO 4406 code 19/17/14 to avoid abrasion of the precision lands. It mounts on the ISO 4401-AB-03-4-A interface that corresponds to the CETOP 3 (NFPA D03) pattern, allowing interchange with other subplate components. Proper sealing demands a mounting surface flatness of 0.013 mm and a surface finish of 1.1 micrometers. Fastening is handled by M5-0.8 (10-24 UNC-2B) bolts tightened to 4.5–6.0 N·m, securing the body without distorting the casting.
