4WEH32D6X/OF6EW110N9DA

The 4WEH32D6X/OF6EW110N9DA valve belongs to the WEH Directional Spool Valves series from Bosch Rexroth and routes pressurized fluid in hydraulic automation circuits. It is built as an NG32 unit, a size that matches large-flow manifolds. A four-way configuration provides separate pressure, tank, and dual work ports for actuator control. The spool offers two discrete positions so cylinders or motors can alternate between operating states. Fast response is supported by a pilot flow requirement of 45 l/min. The assembly shifts reliably once a minimum pilot pressure of 10 bar is available and can pass up to 1100 l/min at 70 bar without exceeding its performance limit.

The valve accepts a continuous operating pressure of 280 bar at ports P, A, and B. Its pilot stage is rated for a maximum of 250 bar, enabling use in high-pressure control loops. These pressure ratings allow the spool to shift under demanding load conditions without undue wear. Installation is carried out with the ISO 4401-10-09-0-05 mounting pattern for direct interface with standardized subplates. The fixed interface also simplifies replacement tasks during scheduled maintenance. Together, the high pressure capability and standardized mounting define the operational envelope of the 4WEH32D6X/OF6EW110N9DA within complex hydraulic automation schemes.
