The DG4V36CUB20S300 directional control valve belongs to the DG4 Directional Valves series and is manufactured by Vickers for hydraulic automation circuits. It employs a spring-centered spool designated arrangement C, holding the spool at neutral when the solenoids are de-energized. Spool function code 6 blocks the pressure port while routing both work ports to tank, allowing rapid pressure release during standby. The valve handles a maximum flow of 40 l/min (10.5 US gpm), enabling service on medium-capacity actuator lines. Pressure capability reaches 350 bar on pressure and work ports and 210 bar on the tank port, so the unit can be installed in high-pressure manifolds without external relief devices. Continuous operation is supported by a 100 percent duty cycle, and each solenoid draws 30 W, which simplifies thermal calculations for control enclosures. An enclosure rating of IP67 protects the coil and internal wiring against dust ingress and temporary immersion, maintaining reliability in harsh mobile equipment.
The B port includes a 2.0 mm orifice that limits pilot flow and stabilizes actuator deceleration on return strokes. Electrical termination is provided through an ISO 4400 (DIN 43650) connector, allowing quick removal during maintenance. The encapsulated coil is built to Class F temperature limits while the windings meet Class H insulation ratings, extending service life under elevated oil and ambient temperatures. To preserve internal clearances, the hydraulic fluid must not exceed ISO 4406 cleanliness code 19/17/14. The valve mounts on an ISO 4401-AB-03-4-A interface that follows the CETOP 3 / NFPA D03 pattern, so it can be fitted to standard subplates without adapter blocks. With both solenoids installed, the assembly weighs 2.2 kg, permitting manual replacement without lifting gear.
