The 4WE6J6X/EW110NK4/B08V belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth for switching and blocking flows in hydraulic automation circuits. A solenoid coil rated for 110 V AC at 50/60 Hz actuates the spool, drawing 0.52 A on 50 Hz supply and 0.39 A on 60 Hz supply. The valve withstands up to 350 bar on pressure, A, and B ports, and passes a maximum flow of 60 l/min through its metering slots. A 0.8 mm throttle insert in port P, identified by the B08 code, stabilizes inlet flow when rapid pressure changes occur. Manifold mounting follows the ISO 4401-03-02-0-05 pattern, and the NFPA T3.5.1 D03 standard keeps the interface compatible with common size 03 sub-plates.
The unit operates in ambient temperatures up to 50 °C with its FKM seal set, while hydraulic fluid can reach 80 °C without compromising function. Protection class IP65 prevents dust ingress and low-pressure water jets from affecting the enclosure. Electrical termination uses the DIN EN 175301-803 K4 connector, allowing simple coil replacement and wiring. A switch-off overvoltage limit of 500 V safeguards the winding insulation during de-energization. Tank port T is rated for 160 bar so return lines stay within safe limits, and an MTTFd of 300 years indicates a long statistical service life under typical duty cycles.
