The PA5DG4S4LW-0133C-H-60-S525 is a directional control valve in the Directional Control Valves series from Vickers that directs hydraulic flow in automated machinery. It is solenoid-operated so the spool shifts in response to an electrical signal for remote control. The single-stage layout shortens the flow path and keeps response times low. A spring-centered three-position mechanism returns the spool to neutral when power is removed, providing fail-safe centering. Spool type 33 establishes the A-B-T flow pattern used for common cylinder circuits. A waterproof manual override designated by the H option permits local actuation during electrical outages while keeping moisture out. The 5-pin male PA5 connector supplies a keyed plug that resists wiring errors, and leads are shielded inside a 1/2 NPT conduit housing marked W to prevent abrasion. Subplate or manifold mounting lets technicians replace the unit without disturbing pipe work, and the ISO 4401-05 interface aligns the ports with standard hydraulic bases.
The valve tolerates a maximum operating pressure of 3600 psi, allowing it to run in high-pressure power units. A tank port rating of 1000 psi lets the return line carry back-pressure that may be present in restricted reservoir plumbing. Its 25 gpm flow capacity supports medium-size actuators without excessive pressure loss. Compatibility with petroleum oils matches the fluid typically stocked in industrial reservoirs, while a cleanliness level of ISO 4406 20/18/15 protects the spool and body from abrasive wear. An operating temperature window from 20 °C to 50 °C keeps the internal clearances within design limits across normal plant conditions.
