The 3WH6A5X/B08/5 directional spool valve is produced by Bosch Rexroth for the WEH Directional Spool Valves series. It is a hydraulically actuated unit intended to route fluid in automated circuits. The valve conforms to the D03 Cetop size and matches the ISO 4401-03-02-0-05 mounting pattern, enabling drop-in installation on standard sub-plates. It is built with nominal size 6 flow paths and carries spool symbol A to define its internal geometry. Two switching positions allow the operator to select between flow states across the three available ports. Under steady service the component tolerates up to 315 bar and passes as much as 60 liters per minute without exceeding rated limits.
For pilot control, the valve accepts pressures down to 6 bar and up to 200 bar, with a pilot volume of 1.23 cubic centimeters required per shift. The tank port may be exposed to 160 bar, so return lines can remain pressurized in closed loop systems. An internal throttle orifice measuring 0.8 millimeters stabilizes actuation speed by metering pilot flow. Sealing elements are manufactured from NBR to resist common mineral oils used in power units. Overall mass is 1.26 kilograms, supporting compact manifold layouts while maintaining adequate rigidity.
