The 4WEH32U6X/6EW110N9TS2DA valve belongs to the WEH Directional Spool Valves series from Bosch Rexroth and is used to route hydraulic flow in automated machinery. The electro-hydraulic actuation shifts a NG32 main stage that carries a 4-way port layout, providing pressure, tank, and two service lines for bidirectional cylinder control. A spring-centered spool returns to a neutral position when pilot power is removed, keeping actuators stationary. The High-Power 6E pilot valve receives oil from an external pilot supply, and the spent pilot oil is returned internally to simplify plumbing. Rated pressure capability reaches 280 bar on ports P, A, and B, while maximum flow is 1100 l/min to satisfy high-demand circuits handling large loads.
The pilot stage accepts up to 250 bar and begins to operate at 8.5 bar, enabling reliable function across a wide pressure window. A pilot flow of 45 l/min supports the shortest switching time, and discharge control S2 allows adjustment of that response by metering oil to tank. The ISO 4401-10-09-0-05 mounting pattern aligns with standard manifolds, eliminating the need for adapter plates. A concealed manual override lets technicians move the spool mechanically during setup or servicing without exposing the mechanism. Installed hardware must support the 41.0 kg mass of the two-solenoid assembly to avoid manifold distortion under vibration.
