4WE6D6X/OFEG24N9K4/B10V CSA

The 4WE6D6X/OFEG24N9K4/B10V CSA valve is produced by Bosch Rexroth as part of the WE Directional Spool Valves series. It directs hydraulic flow in automated circuits and is sized to the nominal size 6 format for use on compact manifolds. Installation aligns with the ISO 4401-03-02-0-05 subplate pattern so mounting plates can be standardized across machines. The design also matches the NFPA T3.5.1 R2-2002 D03 interface, allowing interchangeability with North American manifolds. Flow capacity reaches 80 l/min in direct-current operation, supporting medium-duty actuator groups. A throttle insert in port P with a 1.0 mm orifice is included to moderate inrush flow and stabilize downstream pressure. The solenoid is rated for a coil voltage of 24 V DC, and it accepts a ±10 % variation so supply regulators can be relaxed. Continuous energizing is permitted because the coil is specified for a 100 % ED duty cycle. Power consumption is 30 W, keeping panel supply demands modest.

Electrical hookup uses the DIN EN 175301-803 connector code K4, simplifying quick replacement in field service. When mated, the housing achieves an IP65 enclosure rating, guarding the coil against dust and low-pressure water jets. The valve body is sealed with FKM elastomers, making it compatible with higher-temperature synthetic fluids. The maximum surface temperature allowed on the coil is 120 °C, so ambient heat and duty cycles must be controlled to stay within this limit. Hydraulic ports P, A, and B withstand pressures up to 350 bar, enabling the unit to drive cylinders in high-pressure circuits. Return-line port T is limited to 210 bar, which should be considered when sizing back-pressure accumulators. The internal throttling arrangement helps maintain these pressure limits during switching. Combined with its standardized interfaces, these pressure and protection features tailor the valve for reliable control in industrial automation environments.
