The 4WEH10HD4X/OF6EW110N9TDAL directional spool valve is produced by Bosch Rexroth for the WEH Directional Spool Valves series. It is an electro-hydraulic unit that directs oil flow in automated hydraulic circuits. The valve is supplied in NG10 size and provides two spool positions to establish or block flow paths as commanded. A porting pattern compliant with ISO 4401-05-05-0-05 allows direct mounting on standard sub-plates, and installation must be horizontal to maintain correct pilot drainage. Flow rates up to 160 l/min can pass through the main ports while the main spool is shifted by hydraulic return pressure. Pilot operation uses an external X supply with internal Y return, and the pilot stage is held in position by a detent without a spring. The pilot circuit requires at least 7 bar to actuate.
Maximum operating pressure on the P, A, and B lines reaches 280 bar, matching the permitted back pressure of 280 bar on the T port for consistent load handling. The pilot circuit tolerates up to 250 bar, and the internal Y gallery withstands 160 bar, ensuring safe feedback to tank. Mounting screws must be tightened to 12.5 Nm to secure the valve against dynamic loads. Functional safety is supported by a mean time to dangerous failure of 100 years for this WEH type. These pressure and fastening limits allow the pilot stage to function without leakage or distortion during extended duty in automated hydraulic machinery.
