The 4WE6J6X/EW24N9K4/H18 valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and shifts hydraulic flow paths in automated systems. It tolerates 350 bar at the P, A, and B ports, while the return line can operate up to 160 bar, enabling use in high-pressure circuits. A maximum flow of 60 l/min supports medium-speed actuators without excessive pressure drop. Actuation comes from a high-power wet-pin solenoid, and continuous energizing is permitted by a 100 % duty cycle. Electrical power reaches the coil through a DIN EN 175301-803 K4 connector that uses a 3-pole (2 + PE) pinout, ensuring straightforward wiring. The winding accepts voltage variations within ±10 % of nominal, and a switch-off overvoltage limit of 500 V protects insulation during de-energizing.
The valve attaches to sub-plates with an NFPA T3.5.1 D03 interface and follows the ISO 4401-03-02-0-05 porting pattern, aligning its ports with common manifolds. An IP65 protection class seals the enclosure against dust and low-pressure water jets when the connector is properly fitted. A concealed manual override labeled N9 allows technicians to shift the spool during setup without exposing internal parts. Hydraulic fluid must meet ISO 4406 cleanliness class 20/18/15 to prevent wear and sticking. During operation the coil surface may reach 120 °C, a factor that influences ambient temperature planning. The complete assembly with two solenoids weighs 1.95 kg, helping keep manifold banks compact.
