4WE6J6X/EG12N9K4/A12H12/62SO43A-1096

The 4WE6J6X/EG12N9K4/A12H12/62SO43A-1096 valve, produced by Bosch Rexroth for the WE Directional Spool Valves series, directs hydraulic flow for automation tasks such as actuator extension and retraction. The product is manufactured in nominal size 6 so it fits compact ISO 4401-03 subplates and keeps manifold layouts small. Its porting pattern matches ISO 4401-03-02-0-05, which enables drop-in replacement on common industrial bases. A 12 V DC solenoid coil energizes the spool, making the valve compatible with mobile or battery-supplied machinery, and the device draws a rated 2.5 A to reach full magnetic force without exceeding thermal limits. Maximum flow of 80 l/min ensures adequate volume for medium-speed cylinders while limiting pressure loss, and the service ports tolerate up to 350 bar so high-pressure pumps can be used. Dampened switching behavior identified as A12 reduces hydraulic shock during spool movement, extending hose life. Finally, a 1.2 mm throttle insert in port A restrains inrush flow to moderate cylinder acceleration at start-up.

A concealed manual override designated N9 allows technicians to shift the spool manually during commissioning or power loss without exposing the coil to contaminants. The valve carries an IP65 ingress protection rating, which keeps dust and low-pressure water jets away from electrical parts during outdoor operation. Electrical connection is made through a K4 form plug conforming to DIN EN 175301-803, providing quick disconnection during service. Fluid operating temperature from –20 to +80 °C enables year-round use in mobile equipment, and the design accepts oil viscosities between 2.8 and 500 mm²/s so both light and heavy fluids remain controllable. The tank port withstands backpressure up to 210 bar, preventing case distortion when return lines are restricted. A locating hole specified as ISO 8752-3x8-St keeps the body aligned on the manifold to avoid port mismatch. With two solenoids installed the assembly weighs 1.95 kg, allowing single-person installation and minimizing load on compact actuator brackets.
