The 4WE6J6X/EG125N4K4/V/62 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic flow in automated machinery to start, stop, or change actuator movement. The valve is nominal size 6, matching compact subplates and minimizing installation space. A porting pattern compliant with ISO 4401-03-02-0-05 enables direct mounting without adaptor plates. FKM seals allow operation with common fluids and elevated oil temperatures. A maximum flow rate of 80 l/min maintains acceptable pressure drop, and ports A, B, and P withstand up to 350 bar. The tank port tolerates 210 bar, permitting counterbalance circuits. Fluid cleanliness must meet ISO 4406 20/18/15 to reduce wear. A small lockable mushroom button provides a manual override for circuit proving or emergency positioning.
The electromagnetic actuator uses a 125 V DC coil that operates within a ±10 % voltage band, drawing 30 W at the rated power. A 100 % duty cycle permits continuous energization without derating, and the coil surface can reach 120 °C, so nearby wiring must be temperature-resistant. Electrical connection is made with a DIN EN 175301-803 K4 plug for straightforward field wiring. A locating hole for an ISO 8752-3×8 pin holds the valve body in place during dynamic pressure loads. Together, the electrical interface and secure pinning suit the valve for automated directional control duties.
