The 4WH6E5X/V/5 valve is produced by Bosch Rexroth within the WEH Directional Spool Valves series. It is a direct-operated spool valve that switches hydraulic flow paths in automation circuits. Hydraulic actuation removes the need for solenoids and lets pilot pressure move the spool. With nominal size 6 passages, the body matches compact manifolds, yet it withstands a maximum operating pressure of 315 bar for medium-pressure systems. A rated flow of 60 l/min supports clamp, feed, and auxiliary lines without excessive pressure drop. The configuration provides three discrete spool positions to deliver extend, neutral, and retract functions. Spool symbol E defines closed-center porting when centered to isolate actuators. Conformance with CETOP D03 dimensions simplifies interchangeability among European sandwich plates.
Subplate mounting seats the valve on an ISO 4401-03-02-0-05 interface, eliminating adapters during replacement. The NFPA T3.5.1 R2-2002 D03 pattern allows the same unit to fit North American bases. Radial control ports turn pilot hoses toward the manifold side to reduce hose loops in crowded panels. Four working ports provide pressure, tank, and two service lines needed for double-acting cylinders. FKM elastomer seals tolerate high temperatures and aggressive oils, so service life is extended in harsh fluid conditions. An installed mass of 1.62 kg limits additional load on mobile machinery and eases one-person handling during maintenance.
