The 4WE6D6X/EW110RNDL/B12/62 valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic oil flow in automation circuits. It mounts on sub-plates that follow the ISO 4401-03-02-0-05 porting pattern to align pressure and return passages accurately. The solenoid operates on a nominal supply of 110 V AC at 50/60 Hz and draws a steady 0.34 A. Energizing the coil demands 220 VA switch-on power, after which consumption falls to 50 VA holding power. Continuous operation is supported by a 100 % duty cycle and H-class insulation. During prolonged use the coil surface may rise to 120 °C without damaging the winding, and an IP65 enclosure prevents dust ingress and water spray from reaching internal parts.
The hydraulic section tolerates system pressures up to 350 bar while the tank port is limited to 160 bar to protect return lines. A maximum flow of 60 l/min passes through the body, and a 1.2 mm throttle orifice in port P moderates inlet velocity. The spool can shift twice per second, giving a switching frequency of 2 Hz for repetitive machine cycles. Secure mounting is achieved when the fixing bolts are tightened to 7 Nm. Functional safety is reflected in a mean time to dangerous failure of 300 years, confirming long service life in automated hydraulic equipment.
