The DG4V50AMPLT640P10 directional valve belongs to the DG4 Directional Valves series and is manufactured by Vickers for hydraulic automation circuits that require reliable flow routing. It accommodates mineral oil or water-glycol so it can be installed in standard or fire-resistant systems. The spool offers 2 positions, allowing an actuator to alternate between two discrete flow states. A single solenoid shifts the spool, and its wet armature construction immerses moving parts in fluid to reduce wear. The T-coil accepts an AC supply that is internally rectified to DC, giving installers flexibility with available power sources. Up to 240 switching cycles per minute are supported, permitting rapid machine sequencing. There is also a manual override so technicians can move the spool without electrical power during setup or servicing.

The valve sustains a maximum working pressure of 31.5 MPa on the supply ports, making it suitable for high-pressure lines. The T port withstands back pressure to 15.7 MPa, preventing functional loss when return circuits run at elevated pressure. Installation uses the ISO 4401-AC-05-4-A interface, ensuring compatibility with common subplates. Four M6 bolts tightened to a 14 mm thread depth secure the body to the mounting face and maintain gasket compression. A 1.0 mm orifice in the P port meters pilot flow to stabilize spool movement and damp pressure spikes. Electrical conductors enter through two G1/2 conduit ports, providing sealed wiring access in industrial environments.
