4WE6J6X/EW110NDAL

The 4WE6J6X/EW110NDAL model is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. It directs pressurized oil to actuator ports in hydraulic automation where reliable switching is required. The valve matches a nominal size 6 interface, allowing compact installation on sub-plates designed for NG6 circuits. Its mounting layout follows the ISO 4401-03-02-0-05 porting pattern, simplifying interchange with other NG6 devices. Channels P, A, and B withstand operating pressures up to 350 bar so the unit can be fitted to high-pressure work circuits. Flow capacity reaches 60 l/min, enabling moderate actuation speeds without excessive pressure drop. The hydraulic section tolerates fluid temperatures from –20 °C to +80 °C, supporting both cold-start conditions and elevated oil temperatures. Continuous duty is supported by a 100 % ED rating, so the spool can remain energized without thermal pause. Cleanliness requirements are limited to ISO 4406 (c) 20/18/15 to protect the precision spool fit, and the housing carries an IP65 protection class for secure operation in dusty or moist surroundings.

The valve uses a 110 V AC solenoid rated for 50 or 60 Hz to suit common plant supplies. Voltage may vary by ±10 %, and the coil still maintains correct shifting force within that band. When power is applied, the circuit draws a switch-on power of 220 VA, after which holding power falls to 50 VA to reduce heat build-up. At 50 Hz the steady current is 0.52 A, while at 60 Hz it drops to 0.39 A, ensuring predictable load sizing for control transformers. Electrical connection is provided through a DAL conduit entry with a 1/2-14 NPT thread and an integrated position indicator that eases commissioning. The tank port is limited to 160 bar, letting designers size return lines and cooler elements accordingly. Together these electrical and hydraulic ratings define the boundaries for safe integration of the 4WE6J6X/EW110NDAL valve in automated machinery.
