The 4WE6D6X/OFEG24N9K4/B10 CSA valve is built by Bosch Rexroth for the WE Directional Spool Valves series. It channels pressurized fluid to hydraulic actuators in mobile and industrial automation. The subplate mounting interface follows ISO 4401-03-02-0-05 so it can fit standard size 6 manifolds. Flow capacity reaches 80 l/min on direct current operation, supporting medium flow circuits. The p, a, and b ports tolerate operating pressures up to 350 bar, while the t port is limited to 210 bar to protect return lines. A 1.0 mm throttle orifice in the pressure port moderates inlet flow as identified by the B10 code. The solenoid requires a 24 V DC supply and draws a rated current of 1.25 A, resulting in a nominal power demand of 30 W. These parameters allow stable spool shifting under full system load.
Its electrical connection uses the K4 plug according to DIN EN 175301-803, simplifying wiring in enclosures. The coil is built to insulation class F and can run at a surface temperature up to 120 °C without degradation. Continuous operation is possible because the duty cycle is 100 % in S1 service. A concealed N9 manual override permits local actuation during commissioning or power loss. Maximum switching frequency is 4.2 cycles per second, enabling responsive directional changes in servo loops. Environmental sealing meets IP65 so the assembly resists dust and water jets when fitted with the appropriate connector. The twin-solenoid version weighs 1.95 kg, easing handling during maintenance. Together these attributes support reliable hydraulic circuit control in harsh production settings.
