The DG4V37CMP7H750 valve belongs to the DG4 Directional Valves series from Vickers and shifts hydraulic flow between pressure, actuator, and tank lines in automated equipment. Its solenoid operates on 24 VDC at 30 W, and the 100 % ED duty cycle lets the coil remain energized continuously. The coil is encapsulated to Class F standards and uses Class H insulation so thermal limits are maintained during prolonged service. A wet-type armature reduces shock and noise, while electrical connection is provided through male Packard Weatherpak pins for sealed field wiring. The spool is spring centered, and in the center position pressure is directed to both work ports while the tank line is blocked.
The valve mounts to manifolds that follow the ISO 4401-AB-03-4-A pattern, which matches the CETOP 3 / NFPA D03 size for interchangeability. Proper installation uses M5 (10-24 UNC) screws, and the mating face must maintain a flatness within 0.013 mm and a surface finish of 1.1 micrometer to prevent leakage. Lines P, A, and B can be pressurized to 350 bar, while the tank port is limited to 210 bar (3000 psi) to protect return components. These limits, combined with the mounting standard, allow the valve to fit medium-pressure mobile and industrial systems without compromising compactness.
