The 4WH6C5X//5 valve belongs to the WEH Directional Spool Valves series produced by Bosch Rexroth and is intended for hydraulic automation tasks that require precise flow direction. The unit is hydraulically actuated and works with nominal size 6 passages, providing four working ports for pressure, tank, and two service lines. A C-type spool establishes the crossover flow pattern, while two switching positions alternate those paths under control commands. When attached to a subplate, the valve tolerates up to 315 bar on the pressure, A, and B ports and passes a maximum flow of 60 l/min. Switching can occur at 2 Hz without overstressing internal components, and the design permits installation in any orientation to simplify manifold layout.
Additional limits are governed by pilot circuitry: the control stage requires between 6 bar and 200 bar and encloses 1.23 cm³ of pilot volume, allowing quick pressure changes during shifts. The tank port withstands 160 bar so back-pressure cannot force fluid past seals, which are made from NBR to suit standard mineral oils. A base pattern of ISO 4401-03-02-0-05 grants compatibility with CETOP 3 mounting surfaces found in many industrial machines. These attributes enable the 4WH6C5X//5 valve to integrate into compact hydraulic panels that demand predictable flow switching and reliable two-position service.
