The M-3SED6UK1X/350CG110N9K4 valve is part of the M-SED Poppet Valves series manufactured by Bosch Rexroth for hydraulic automation tasks that require straightforward on/off flow control. It performs a 3/2 directional poppet function and leaves the flow path open when de-energized because the start position is normally open. Actuation is handled by a wet-pin DC solenoid with a detachable coil rated at 110 V DC, and the coil accepts a voltage tolerance of ±10 %. When only 120 V 60 Hz mains are available, the unit can be powered through a rectifier to maintain the correct DC supply. The solenoid draws 30 W and is designed for a 100 % duty cycle, so it can remain energized continuously without overheating. System pressure up to 350 bar can be applied without impairing sealing or shifting reliability.
Three main ports provide the pressure, actuator, and return connections needed in compact manifolds. A concealed manual override lets maintenance personnel shift the valve mechanically during commissioning or power loss. The design omits a check valve insert and a throttle insert, so additional line components must be used if flow damping or reverse blocking is required. No position switch is included, which simplifies wiring and reduces envelope size, while the electrical interface follows DIN EN 175301-803 for standard cable plugs. All dynamic and static seals are manufactured from NBR to resist common mineral hydraulic oils and maintain low leakage at rated pressure.
