The PA4DG4S4W-012N-H-61-S558 valve belongs to the Directional Control Valves series manufactured by Vickers for hydraulic automation circuits that require reliable on-off flow routing. It is solenoid operated, so an electrical signal moves the spool without mechanical linkage. A single stage layout keeps the flow path direct, while spool type 2 forms the standard A-B-P-T connections used in cylinder actuation. The spool is held in position by a no spring detented arrangement, meaning it remains where last driven until the solenoid is energized again. There is no manual override, so service personnel cannot shift the element by hand, and no spool position monitor is provided, so external sensing is needed when feedback is mandatory. The ISO 4401-05 interface matches common subplates, and the subplate/manifold mounting style lets the valve integrate with stacked manifolds. It is compatible with petroleum oils, which simplifies fluid selection in conventional power units.
The valve handles a maximum flow rate of 25 gpm to support medium-capacity actuators, and it withstands operating pressures up to 3600 psi for high-pressure mobile or industrial systems. A tank port rating of 1000 psi protects the return side from excessive backpressure. Required fluid cleanliness is 20/18/15 per ISO 4406, limiting particulate levels to preserve spool clearances and reduce wear. Electrical connection is achieved with a flying lead coil wire housing, allowing quick field wiring without additional connectors. Operating temperature spans 70 °F to 122 °F, so the unit functions correctly in reservoirs maintained within typical ambient ranges. These characteristics combine to provide controlled flow direction, pressure capability, and environmental tolerance for automated hydraulic machinery.
