The PBDG4S4L-012A-50-H valve is produced by Vickers as part of the Directional Control Valves series. It directs hydraulic flow in automated circuits by shifting a single stage Spool 2 element through solenoid actuation. The solenoid operates on a 24 VDC coil that is supplied through a flying lead connection, enabling straightforward wiring inside machine enclosures. Mounting follows the ISO 4401-05 interface so the body fits standard subplate or manifold patterns. A spring offset holds the spool in its default position until the coil is energized, and an internal orifice of 0.047 in conditions pilot flow for consistent shift speed. The design works with petroleum oils that meet a cleanliness level of 20/18/15 according to ISO 4406, ensuring reliable movement and preventing wear.
The valve supports system pressures up to 3000 psi on the service ports while the tank port is limited to 1000 psi, allowing it to handle common industrial power units. A maximum flow capacity of 20 gpm can be routed without exceeding the rated pressure drop. Operating temperature is capped at 50 °C, matching typical reservoir limits in mobile and factory machinery. Buna-N seals contain the fluid and provide chemical compatibility with the specified petroleum media. These parameters complete the functional envelope of the PBDG4S4L-012A-50-H for hydraulic automation tasks that require precise on-off directional control under moderate flow and pressure conditions.
