The M-3SEW10C1X/420MG24N9K4 CSA valve is produced by Bosch Rexroth within the M-SEW Poppet Valves series. It functions as an on-off element in hydraulic automation by opening or closing flow paths to actuators. The valve provides three main ports to connect pressure, tank, and service lines. Its solenoid is a detachable high-power air-gap design that supplies the force needed to shift the poppet under a maximum operating pressure of 420 bar. The coil draws 30 W at a nominal 24 V DC, and the ±10 % voltage tolerance keeps operation stable when supply levels vary. Continuous energization is possible because the duty cycle is 100%, while a permitted coil surface temperature of 120 °C prevents thermal damage. An IP65 protection class shields the housing from dust and low-pressure water jets, supporting reliable service in exposed machine areas.
The hydraulic section is intended for mineral oil, and NBR seals are fitted to maintain compatibility with that fluid and limit external leakage. Electrical hookup is completed through a DIN EN 175301-803 K4 connector, allowing quick replacement of the detachable coil. A concealed manual override lets maintenance staff shift the valve without power, yet its recessed form protects against accidental actuation. No check-valve insert is fitted, so reverse-flow blocking must be handled by external components, and no throttle insert is present, meaning flow throttling must be provided elsewhere in the circuit. The design also omits a position switch, so feedback about poppet state is not available to the control system. Together these features deliver a straightforward poppet valve that focuses on dependable switching while relying on auxiliary devices for additional flow conditioning or status monitoring.
