The 4WEH22Y7X/6EW110N9EDA/B10 directional spool valve is produced by Bosch Rexroth as part of the WEH Directional Spool Valves series and is intended to route hydraulic flow in automated machinery. Its nominal size is NG25, so it fits manifolds drilled for that cavity. The porting follows ISO 4401-08-08-0-05 to maintain interchangeability with common subplates. A maximum operating pressure of 280 bar on ports P, A, and B lets the unit work in high-pressure supply lines. With symbol Y at 280 bar the valve carries up to 400 l/min, minimizing pressure loss in large flow circuits. The hydraulic fluid must meet cleanliness class ISO 4406 (c) 20/18/15 to protect the spool and bore from abrasion. The mating subplate surface needs an Rz value no greater than 4 µm to achieve leak-free sealing under load.
Pilot control tolerates a maximum of 210 bar, preventing overloading of the pilot stage. Consistent actuation begins at a minimum pilot pressure of 11 bar when a two-spool design with an external X port and return springs is used. Each shift consumes 15.28 cm³ of pilot oil, a figure used when sizing the pilot supply. A 1.0 mm throttle insert designated B10 can be installed to restrict pilot flow and damp pressure spikes. Assembly requires six M12 × 60 screws that clamp the valve to the manifold, and each screw must be tightened to 100 Nm so gasket compression is uniform without damaging the threads.
