The 4WEH10J4X/6EG24N9TS2K4/V valve belongs to the WEH Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation circuits that require precise flow control. This NG10 valve uses electro-hydraulic actuation, driven by a 6E pilot valve that responds to a 24 V DC supply to shift the spool remotely. It carries a maximum flow capacity of 160 l/min when operated with symbol J, making it suitable for medium-size manifolds. Subplate mounting is supported, and the port block matches the ISO 4401-05-05-0-05 pattern so it can be installed on standard bases without re-machining. The hydraulic circuit must be filled with HL or HLP oils according to DIN 51524, and a concealed manual override identified as N9 enables on-site actuation if electrical power is unavailable.
The pilot stage functions between 12 bar and 250 bar, with the lower limit needed to overcome the spring centering force and the upper limit defining allowable pilot pressure. FKM seals provide chemical resistance and temperature stability for long service life with the specified fluids. Installation uses four M6 × 45 screws per ISO 4762, and each screw should be tightened to 12.5 Nm to maintain clamping force and prevent leakage. The assembled unit with two solenoids and spring centering weighs 6.8 kg, so the subplate must support that load. Functional safety is indicated by an MTTFd of 100 years, reflecting a very low probability of dangerous failure during normal operation.
