PA5DG4S4LW-012A-H-60-S471

The PA5DG4S4LW-012A-H-60-S471 valve is produced by Vickers within the Directional Control Valves series. It directs pressurized oil to selected actuator ports in hydraulic automation circuits. Solenoid operated actuation converts electrical signals into spool movement so that flow reversal can be commanded from a control panel. A 5-pin connector forms the electrical interface, allowing quick disconnection during maintenance. Spool type 2 sets the internal land geometry to establish two discrete flow patterns, while the spring offset P-A arrangement biases the valve to send pump flow to port A when the solenoid is de-energized. The ISO 4401-05 / NFPA D05 mounting interface aligns the ports with common sub-plates, simplifying manifold installation.

Overall dimensions are controlled for tight machine layouts; the height is 3.850 in, the width is 2.580 in, and the length is 6.840 in, permitting side-by-side stacking on standard rails. Buna-N seals resist petroleum-based fluids and retain flexibility over the expected temperature range, preventing external leakage at interface joints. An integrated indicator light confirms coil energization so technicians can verify actuation status at a glance without test equipment. These dimensional, sealing, and feedback features help the PA5DG4S4LW-012A-H-60-S471 fit compact power units, maintain hydraulic integrity, and provide visual diagnostics during routine operation.
