The DG4V-3-0BL-M-W-B-40 valve from Vickers belongs to the DG4 Directional Valves series and controls hydraulic flow in automated machinery. The 0 open-center spool lets system pressure bleed to tank when the valve is neutral, reducing standby heat. A BL left-hand spring arrangement returns the spool to center when the solenoid is de-energized, simplifying single-ended actuation. The wet armature solenoid design immerses the plunger in fluid to damp noise and extend service life. Coil encapsulation to Class F shields the windings against vibration, while Class H insulation allows operation at higher ambient temperatures. A continuous 100 % duty cycle permits the coil to stay powered without overheating, and power consumption is limited to 30 W for modest electrical demand. Reliable pull-in is maintained when coil voltage falls to 90 % of its rating, supporting installations with long cable runs.
The valve handles pressures up to 350 bar (5000 psi) on ports P, A, and B, making it suitable for high-pressure circuits. Hydraulic cleanliness must meet ISO 4406 19/17/14 to minimize spool sticking and wear. The mounting interface follows ISO 4401-AB-03-4-A, ensuring direct fit on common subplates, and the porting pattern matches CETOP 3 / NFPA D03 layouts for standardized flow paths. Electrical termination is provided by a 1/2 in NPT thread in the wiring housing, giving a secure conduit entry. Typical energizing response is 60 ms, while de-energizing occurs in 40 ms to restore neutral quickly. These timings, combined with the pressure rating, filtration standard, and interface features, yield predictable control behavior in automated hydraulic circuits.
