4WE6D6X/OFEG24K4/62 CSA

The 4WE6D6X/OFEG24K4/62 CSA directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic flow in automated machinery. The valve is built in size 6 to match manifold cavities common in compact power units. Actuation is carried out by a wet-pin solenoid so the coil remains separated from the hydraulic fluid while the armature runs in oil for reduced wear. The coil is designed for a nominal voltage of 24 V DC and accepts a ±10 % variation to accommodate typical supply fluctuations in control cabinets. A continuous power draw of 30 W keeps response time consistent without excessive heat buildup. Electrical hookup is through a DIN EN 175301-803 connector with three power pins and a protective earth, allowing quick plug-in replacement. The spool includes a mechanical detent, identified by the OF code, so the selected flow path is held without power during intermittent machine cycles. Hydraulic interface follows the ISO 4401-03-02-0-05 porting pattern which aligns with standard CETOP 3 subplates.

The valve handles service conditions typical of high-pressure circuits. It permits a maximum flow of 80 l/min under direct current excitation while maintaining stable spool positioning. Pressure capability reaches 350 bar on the P, A, and B ports to support modern high-density pumps. The T port is limited to 210 bar, guiding designers when sizing return lines. Ingress protection is rated at IP65 so dust and low-pressure water jets cannot reach the electrical parts once the connector is properly fitted. The assembly conforms to protection class I under VDE 0580, meaning a protective earth conductor is required for safety. Coil insulation withstands surface temperatures up to 120 °C, enabling continuous duty in warm manifolds. Total mass of both solenoids is 1.95 kg, light enough for stack mounting on mobile equipment without reinforcement.
