The 4WE6H6X/EW110NDK25L valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth. It routes pressure and return lines to cylinders or motors in automated hydraulic equipment. The solenoid coil is rated for 110 V at 50 or 60 Hz so it can connect directly to common plant power. A voltage tolerance of ±10 % keeps actuation reliable during supply fluctuations. Continuous operation is permitted because the duty cycle is 100 %. Current draw equals 0.34 A on 50 Hz supplies and 0.39 A on 60 Hz supplies, data used when sizing power supplies and protection devices. During energization the circuit must provide 220 VA of switch-on power; once the armature is pulled in the holding power drops to 50 VA to reduce heating. A central 5-pole Mini-Change connector forms the electrical interface for fast plug-in wiring. A manual override lets maintenance staff shift the spool without power for test or emergency procedures.
The hydraulic side supports a maximum flow of 60 l/min so medium-size actuators can move at design speed. Working ports P, A, and B withstand up to 350 bar, while the tank port is limited to 160 bar, allowing use in high-pressure circuits with moderated return pressure. The spool may be shifted up to 2 times per second, a switching frequency that prevents excessive wear on the electromagnetic drive. An IP65 housing blocks dust ingress and water jets, permitting installation on exposed machinery. Mounting interfaces follow the ISO 4401-03-02-0-05 pattern and match the NFPA T3.5.1 D03 standard, which simplifies exchange with other subplate valves. These interface and protection characteristics ensure dependable integration within modular hydraulic manifolds.
