The 4WEH32L6X/6EW110N9TS2DAL/P4.5V CSA is manufactured by Bosch Rexroth within the WEH Directional Spool Valves series. It directs hydraulic flow in automated machinery through electro-hydraulic actuation, shifting a 4-way spool on command. Nominal size NG32 determines the mounting footprint and channel diameters that match high-capacity circuits. A flow limit of 1100 l/min at 70 bar allows rapid cylinder or motor movement without excessive pressure drop. The spool carries symbol L, indicating the overlap pattern selected for moderate leakage and smooth transition. The valve receives pilot energy from an external X port, and an internal T path conducts the pilot oil back to tank to minimize external hoses. Pilot control tolerates pressures up to 250 bar, while a spring-centered assembly needs at least 8.5 bar to overcome the centering force and shift. Manifold mounting follows ISO 4401-10-09-0-05 so the unit fits standard NG32 subplates.
A concealed N9 manual override lets operators move the spool mechanically when electrical signals are absent. Switching time can be trimmed with the S2 discharge control, enabling the designer to balance response speed against pressure shock. A preload valve that cracks at 4.5 bar releases trapped oil in the pilot stage and stabilizes shifting. System cleanliness must achieve ISO 4406 20/18/15 to prevent scoring on the precisely ground lands. FKM sealing permits hydraulic fluid temperatures up to +80 °C for elevated-temperature service. An external surface coating up to 100 µm thick resists corrosion and abrasion during long-term use. These specific settings govern installation, maintenance, and performance behavior under continual industrial duty.
