The H-4WEH25M6X/6EW110N9S2K4 directional valve belongs to the WEH Directional Spool Valves series and is produced by Bosch Rexroth. It is intended to route pressurized oil in automated hydraulic circuits that need dependable four-way switching. The valve performs this task with a 4-way function that connects pressure, tank, and two work ports as required. Its nominal size NG25 defines the flow section and matches manifolds machined to the ISO 4401-08-08-0-05 porting pattern. Inside the body, a spool with the M symbol creates three selectable flow paths, and the unit provides three spool positions to place the actuator in extend, neutral, or retract states. A maximum operating pressure of 350 bar lets it work in high-pressure machinery, while a peak flow capacity of 650 l/min at that pressure keeps pressure losses low in large cylinders. With two solenoids fitted, the valve weighs 19.0 kg, which must be considered when mounting on a subplate.
Pilot control details support precise timing and safe return of the spool. Pilot oil enters externally through port X and leaves externally through port Y, separating the pilot loop from main lines. The pilot stage tolerates up to 210 bar and needs at least 13 bar to move the three-position spool, so the control pressure must stay within this window. Electrical actuation is provided through a DIN EN 175301-803 K4 plug, offering quick connection in control cabinets. A concealed manual override identified by code N9 permits manual shifting without protruding hardware that could be damaged. Switching time can be adjusted with the S2 discharge feature, allowing technicians to fine-tune response for machine cycles. Fluid cleanliness must meet ISO 4406 20/18/15 to prevent wear and sticking, completing the operating conditions for this spool valve.
