The M-3SED6UK1X/350CG24N9K4 valve is manufactured by Bosch Rexroth within the M-SED Poppet Valves series. It serves as a compact control element for hydraulic automation where reliable on-off flow management is required. The unit is built as a 3/2 poppet design that is normally open, so fluid passes until the actuator closes the poppet. Actuation is handled by a solenoid, allowing electrical commands to shift the valve without manual intervention. The coil is rated for 24 V DC, making it compatible with common machine power rails, and it accepts a ±10 % voltage variation to keep switching consistent during supply fluctuations. A continuous duty cycle of 100 % lets the coil remain energized indefinitely, while power consumption stays at 30 W so panel designers can size supplies accurately. These features let the valve provide dependable cycle-to-cycle performance in machines that run without interruption.
The electrical interface is a K4 plug conforming to DIN EN 175301-803, which simplifies wiring and supports quick service exchange. When the mating connector is fitted, the assembly achieves an IP65 ingress rating to block dust and water jets in industrial bays. The coil winding withstands temperatures up to 150 °C, guarding against heat from ambient or frequent actuation. Hydraulic sections tolerate operating pressure to 350 bar, enabling use in high-pressure lines. Orientation during installation is optional, so the body can be mounted in any position without affecting function. A concealed manual override identified as N9 allows the poppet to be shifted by hand for setup or fault clearing. NBR seals prevent internal leakage and are compatible with mineral oil fluids of the HL or HLP group. A switching frequency of 15 000 cycles per hour supports rapid sequence tasks without premature wear.
