The 4WP6D5X/OFN/5 valve belongs to the WP Pneumatic Spool Valves series from Bosch Rexroth and directs hydraulic flow in automated machinery. It is pneumatically actuated so compressed air shifts the D-type spool without an electrical solenoid. The nominal size 6 body follows the ISO 4401-03-02-0-05 mounting pattern, allowing quick substitution in standardized manifolds. Four main ports connect to system pressure, service lines, and tank; ports A, B, and P withstand up to 315 bar while port T is limited to 160 bar. Rated flow reaches 60 l/min, giving adequate capacity for medium power circuits. A detent holds the spool after pilot pressure is removed, and unrestricted installation orientation simplifies manifold layout.
The valve includes a manual override so maintenance staff can shift the spool when compressed air is absent. Pilot control needs at least 4 bar and accepts up to 10 bar, with each shift consuming 4.24 cm³ of pilot volume for predictable response time. A switching capability of 7 200 cycles per hour supports rapid duty cycles in packaging or material-handling stations. The required oil cleanliness is ISO 4406 20/18/15, which prevents spool wear and maintains sealing accuracy. Because it can be mounted in any position and switched frequently without external cooling, the 4WP6D5X/OFN/5 suits compact hydraulic manifolds that demand reliable directional control.
