The H-4WEH25E6X/6EW110N9ETK4/10B10D3 directional valve belongs to the WEH Directional Spool Valves series and is manufactured by Bosch Rexroth. It hosts nominal size 25 flow paths to route pressurized fluid in hydraulic automation tasks. The mounting face matches the ISO 4401 porting pattern so the unit fastens directly to standard subplates. Continuous service pressure at ports P, A, and B reaches 350 bar, and the e spool passes up to 650 l/min at that rating to satisfy high-demand actuators. Pilot actuation needs a minimum of 13 bar and endures up to 250 bar, while a separate Y return line may carry 160 bar. A pilot chamber volume of 14.2 cm³ for the spring-centered three-position version determines the amount of oil displaced during each shift. These parameters support rapid and stable spool movement under varying load conditions.
Hydraulic cleanliness is limited to ISO 4406 class 20/18/15 to keep sliding edges free from abrasive wear. The solenoid coil connects through a DIN EN 175301-803 K4 plug, providing a sealed electrical interface. Installation requires six M12 × 60 mounting screws, each tightened to 100 Nm to preserve gasket compression. A Ø 1.0 mm B10 throttle insert can be installed to restrict flow and damp pressure surges, and an internal D3 pressure-reducing valve guards the pilot circuit against over-pressure. The tank port tolerates 250 bar, allowing high back-pressure returns in compact systems. The valve carries a calculated mean time to dangerous failure of 100 years, reflecting the durability expected from the WEH series.
