The M-3SED6UK1X/350CG24N9K4/B20 poppet valve belongs to the M-SED Poppet Valves series from Bosch Rexroth and serves as a 3/2 directional device for hydraulic automation circuits. The UK variant holds the flow path open when de-energized, giving a normally open function until the solenoid is powered. A wet-pin detachable coil rated for 24 V DC accepts a voltage window of ±10 %, draws 30 W, and supports continuous service at a 100 % duty cycle. Hydraulic lines can be pressurized to 350 bar through the valve, and the coil insulation tolerates internal temperatures up to 150 °C during prolonged operation.
Electrical termination is provided through a DIN EN 175301-803 interface, and the unit is supplied without a mating connector so wiring can follow site-specific standards. A concealed manual override enables local actuation while guarding against accidental use. The housing carries an IP65 rating that blocks dust and low-pressure water jets in typical machinery locations. Up to 15 000 switching cycles per hour are possible, suiting high-frequency control loops. System fluid must reach ISO 4406 class 20/18/15 cleanliness to preserve the poppet seat, and a 2.0 mm throttle insert moderates flow to keep downstream pressure stable.
