The 4WEH32D6X/6EW110N9TS2K4 CSA valve belongs to the WEH Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow in automation systems. Its nominal size of 32 defines the interface dimensions, while a 4-way flow path and two switching positions establish the basic operating logic. A porting pattern of ISO 4401-10-09-0-05 allows mounting on standardized subplates for quick replacement. The valve withstands 280 bar at pressure ports p, a, and b so it can serve high-pressure circuits, and it passes up to 1100 l/min at 70 bar with the 2-spool symbol D to support large volume demands. Cleanliness to ISO 4406 20/18/15 is required to keep internal clearances free of abrasive wear, and a unit mass of 17.6 kg with one solenoid influences handling and bracket design during installation.
The solenoid is wired through a DIN EN 175301-803 connector, and a concealed manual override lets technicians shift the spool without energizing the coil. Pilot oil enters externally at port X and returns internally to port T, simplifying external plumbing. The pilot stage tolerates up to 250 bar and needs at least 10 bar to move the 2-spool assembly reliably, while port T itself can hold 250 bar so backpressure does not impede function. A pilot chamber volume of 58.8 cm³ shapes response time, and discharge control S2 provides an adjustment point for switching speed. These characteristics let the valve integrate into high-duty hydraulic machines where precise flow direction, compact wiring, and adjustable actuation are essential.
