The 4WP6C6X//V/5 valve is produced by Bosch Rexroth within the WP Pneumatic Spool Valves series, where it directs hydraulic flow using air pilot signals. Pneumatic actuation shifts the spool once the control line reaches the minimum pilot pressure of 4 bar and maintains motion up to the maximum pilot pressure of 10 bar. Nominal size 6 fixes the interface envelope, and the ISO 4401-03-02-0-05 pattern together with the NFPA T3.5.1 D03 code lets it mount on standard sub-plates. Four main ports provide separate connections for pressure, return, and two work lines, reducing the need for external manifolds. A pilot volume of 4.24 cm³ limits the air required for each shift, which improves reaction time during cycle sequences.
The valve carries a maximum flow rating of 60 l/min to serve medium-capacity cylinders and motors. It tolerates 315 bar on ports a, b, and p, while the tank port endures up to 160 bar, so line sizing can follow common hydraulic practices. A switching frequency limit of 7200 cycles per hour supports fast, repeated direction changes in automated machinery. Installation is allowed in any orientation, giving machine designers freedom in manifold layout. FKM seals resist hot hydraulic oil and many synthetic fluids, extending service intervals. The required fluid cleanliness is ISO 4406 20/18/15 to prevent spool scoring and sticking, preserving the valve’s designed switching accuracy.
