The DG4V50AMP7LH630 valve is produced by Vickers and belongs to the DG4 Directional Valves series. It directs hydraulic flow in automated systems that require reliable shifting between service lines. The D05 (NG10) size fits manifolds designed for medium flow circuits, and a mounting interface conforming to ISO 4401-05, also known as NFPA D05, ensures interchangeability with common sub-plates. Spool 0 establishes the neutral and working flow paths required for standard cylinder control, while the spring is offset to port A so the spool returns to a defined position when the coil is de-energized. A plain manual override lets technicians move the spool during setup or power loss. The solenoid operates on 24 VDC and draws 38 W, allowing integration with typical control power supplies. Class H winding insulation tolerates elevated coil temperatures during heavy duty cycles, and continuous service is supported by a 100 % ED duty rating, so the solenoid may remain energized without cooling intervals.
An ISO 4400 (DIN 43650) connector provides a quick electrical interface and simplifies field replacement. The enclosure achieves an IP65 rating, which shields internal components from dust and low-pressure water jets. Maximum flow capability is 120 L/min (31.5 gpm), enabling the valve to handle medium-capacity pumps, and pressure at ports P, A, and B can reach 315 bar (4500 psi), matching high-pressure industrial circuits. The tank port sustains up to 160 bar, allowing back-pressure in load-holding functions. Typical energize time is 120 ms, giving predictable actuation when the coil receives power, and de-energizing takes 45 ms, permitting rapid return of the spool to its spring offset position. These response times help coordinate the valve with sequential logic in PLC-controlled machinery, and together the pressure, flow, and protection features make the DG4V50AMP7LH630 suitable for demanding hydraulic automation tasks.
