4WE6J6X/EG12N9DAL

The 4WE6J6X/EG12N9DAL valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth for hydraulic automation, where it shifts flow between work ports under electrical command. Its high-power wet-pin solenoid with a detachable coil supplies strong magnetic force for reliable spool movement during continuous duty. The coil operates at a nominal 12 V DC so mobile and battery-powered machines can drive the valve without voltage conversion. A rated current of 2.5 A defines the electrical load the control circuit must provide. The DAL central 1/2-14 NPT electrical connection presents a single entry point that simplifies conduit sealing on compact manifolds. An integrated indicator light confirms energization so maintenance staff can verify actuation at a glance. A maximum switch-off overvoltage of 500 V limits the reverse voltage created when the coil is de-energized, protecting driver electronics. The manifold interface follows the ISO 4401-03-02-0-05 porting pattern, allowing the valve to mount on standard subplates without re-machining, and the mounting face is finished to a surface roughness not exceeding Rzmax 4 micrometers to maintain gasket integrity and prevent external leakage.

The enclosure carries an IP65 ingress rating so internal components resist dust and low-pressure water jets. The valve can be installed in any orientation, easing layout inside confined power units. A concealed N9 manual override lets operators shift the spool during commissioning without exposing the control button to accidental bumps. Flow capacity reaches 80 l/min in direct-current service, making the unit suitable for medium-size actuators. Ports P, A, and B tolerate working pressures up to 350 bar. The tank port is limited to 210 bar so return plumbing must be sized accordingly. To prevent contamination-related wear, the hydraulic fluid must meet ISO 4406 class 20/18/15 cleanliness. A calculated mean time to dangerous failure of 300 years supports long service intervals in safety-critical circuits.
