The 4WEH16J7X/6EG24N9ES2K4/B10V valve belongs to the WEH Directional Spool Valves series from Bosch Rexroth and serves to route pressurized fluid within hydraulic automation circuits. It is produced in nominal size NG16, allowing it to mount on subplates of that category, and matches the ISO 4401-07-07-0-05 porting pattern for interface compatibility. Three distinct spool positions provide neutral and two actuated flow states to control cylinder or motor motion. The unit withstands a maximum operating pressure of 280 bar at ports P, A, and B, while a rated flow capacity of 300 l/min (symbol J, NG16) supports high-volume circuits. Pilot oil is supplied internally through port X so additional external supply lines are unnecessary, whereas the pilot return is routed externally through port Y to keep pilot exhaust separate from the main return flow. Port T tolerates up to 250 bar, ensuring the return gallery can handle elevated back-pressure conditions.
Actuation is provided by 24 V DC solenoids, and the electrical interface uses a DIN EN 175301-803 K4 plug to simplify wiring with common industrial connectors. A concealed manual override (designation N9) permits service personnel to shift the spool mechanically without exposing the control to accidental activation. Pilot circuit limits include a maximum pilot pressure of 250 bar and a minimum of 14 bar, defining the pressure window needed for reliable shifting. The external Y drain line is rated for 210 bar so the pilot exhaust can be routed to tank even under moderate counter-pressure. FKM sealing elements, identified by the suffix V, resist heat and aggressive hydraulic fluids to maintain leakage control. A throttle insert with a 1.0 mm orifice (code B10) meters pilot flow, damping sudden pressure changes and promoting stable spool movement under varying load conditions.
