The M-4SEW10Y1X/630MG24N9K4 poppet valve is produced by Bosch Rexroth within the M-SEW Poppet Valves series and regulates hydraulic flow to automate directional control tasks. It follows a 4/2 Y directional design, providing two switched flow paths for circuit routing. A high-power air-gap solenoid drives the poppets and draws 30 W at a nominal 24 V DC. Voltage tolerance is ±10%, so coil performance remains stable under common supply variations. The duty cycle is rated at 100%, meaning the solenoid can remain energized continuously without overheating. A coil surface temperature limit of 120 °C defines the maximum safe operating temperature for extended service life. Electrical termination is handled through a DIN EN 175301-803 connector that simplifies field wiring. Protection class IP65 shields the housing against dust and low-pressure water jets when the mating connector is fitted.
For service reliability, the hydraulic fluid must meet ISO 4406 cleanliness class 20/18/15 to avoid poppet wear. A concealed manual override identified by code N9 allows local shifting without energizing the coil during commissioning or power loss. The envelope withstands operating pressures up to 630 bar while the tank port is limited to 100 bar, enabling installation in high-pressure circuits with lower return-line ratings. A maximum switching frequency of 3600 cycles per hour supports fast machine sequences. The valve includes NBR seals to resist common hydraulic oils while maintaining low leakage. No spool position monitoring is integrated, so external sensors are required if electrical feedback is needed.
