DG4V33CMP7H750JA100

The DG4V33CMP7H750JA100 directional control valve is manufactured by Vickers within the DG4 Directional Valves series. It shifts hydraulic flow between work ports to automate cylinders and motors in industrial equipment. A spring-centered spool is fitted so the valve returns to its neutral position when the solenoid is de-energized. In this center position, pressure and port B are blocked while port A is connected to tank, a P and B closed, A to T configuration that prevents unintended actuator movement. The wet armature solenoid operates immersed in hydraulic oil, which dampens noise and cools the coil for reliable service. Continuous energization is permitted because the coil is rated for a 100 percent duty factor. A water-resistant manual override is provided, allowing the operator to shift the spool even if electrical power is unavailable. The valve follows the CETOP 3 (NFPA D03) interface standard for interchangeability with common subplates.

For installation, the unit employs subplate mounting so the pressure passages are formed in the base rather than the valve body. The hydraulic face matches the ISO 4401-AB-03-4-A pattern, and four #10-24 UNC-2B bolts secure the housing to the subplate to maintain sealing integrity. Port P, A, and B withstand working pressures up to 350 bar (5000 psi), enabling the valve to control high-force actuators without external reinforcement. The tank port is rated for 207 bar (3000 psi), which accommodates back-pressure commonly seen in return lines. These pressure limits guide system designers in selecting compatible pumps and plumbing. When mounted, the standardized footprint and bolt threads speed service replacement while minimizing downtime. Together with the electrical and functional features outlined earlier, the mechanical and pressure specifications confirm the valve’s suitability for continuous operation in demanding hydraulic automation circuits.
