The M-3SED6CK1X/350CG24N9K4/P is a poppet valve in the M-SED Poppet Valves series manufactured by Bosch Rexroth for hydraulic automation circuits that demand leakage-tight shut-off. Its 3/2 directional poppet design in a normally closed position directs flow between three main ports, allowing controlled actuator movement when the solenoid is energized. A maximum operating pressure of 350 bar permits the unit to work in high-pressure power packs without structural fatigue. The valve accepts HL and HLP fluids according to DIN 51524, and performance remains stable as long as oil cleanliness is maintained at ISO 4406 class 20/18/15. An installed check valve insert prevents reverse flow when the poppet closes, safeguarding upstream components. Continuous service is possible because the solenoid is rated for a 100 percent duty cycle. Electrical activation requires 24 V DC, and the coil tolerates ±10 percent voltage variation so it can cope with minor supply fluctuations.
The wet-pin solenoid with a detachable coil simplifies replacement and keeps moving parts in an oil bath, reducing wear during frequent cycles. Electrical draw is limited to 30 W, minimizing heat generation and easing power budgeting in multi-valve manifolds. The coil insulation withstands temperatures up to 150 °C, so reliability is retained even when mounted near warm hydraulic blocks. A switching frequency of up to 15 000 cycles per hour supports rapid machine sequences without loss of response. Connection is made through a DIN EN 175301-803 K4 plug, giving standardized pin assignment for quick wiring. A concealed manual override, coded N9, lets maintenance staff shift the poppet during commissioning while protecting the button from accidental use. When the mating connector is fitted, the housing meets IP65, ensuring dust-tight sealing and resistance to low-pressure water jets inside plant environments.
