M-3SED6CK1X/350CG24N9K4QMAG24

The M-3SED6CK1X/350CG24N9K4QMAG24 poppet valve is produced by Bosch Rexroth within the M-SED Poppet Valves series. It regulates hydraulic flow for automation circuits that need rapid shut-off and low leakage. The valve employs a 3/2 directional poppet function, and its three main ports support simple control of single-acting cylinders. A wet-pin solenoid with a detachable coil marked C actuates the poppet, letting technicians replace the coil without opening the hydraulic path. When de-energized the unit remains normally closed, identified by the CK code, so pressure stays blocked until the coil is powered. The hydraulic passages are designed for a maximum operating pressure of 350 bar to match medium and high-pressure machinery. Electrical power is supplied at 24 V DC, a common control level that simplifies integration with standard power supplies.

For electrical termination, the coil accepts a DIN EN 175301-803 plug coded K4 that allows quick disconnection during service. If the feed source is alternating current the solenoid draws power through an internal rectifier, avoiding the need for external conversion hardware. The housing can be installed in any orientation, which eases manifold design when space is limited. A concealed manual override labeled N9 provides mechanical actuation for setup or emergency operation without energizing the coil. Position feedback is available for spool “a” under the QMAG24 designation, so controllers can verify that the valve has shifted. NBR sealing elements contain the hydraulic medium and offer compatibility with common mineral oils and many synthetic blends.
