The M-3SED6CK1X/350CG96N9K4/P poppet valve is produced by Bosch Rexroth within the M-SED Poppet Valves series for directional control tasks in hydraulic automation. The function symbol CK identifies it as a valve that blocks flow leak-free in the de-energized position, and the design includes a check valve insert to permit reverse flow when required. Three main ports are provided so the component can be integrated into standard supply, actuator, and tank lines. Actuation is handled by a wet-pin solenoid with a detachable coil, allowing rapid replacement without opening the hydraulic envelope. The coil is rated for 96 V DC, accepts a ±10 % voltage variation, and draws 30 W during steady operation. Continuous service is supported by a 100 % duty cycle, while a maximum coil temperature of 150 °C protects the winding insulation during prolonged energization.
System interfaces are simplified by a DIN EN 175301-803 K4 plug, which forms the electrical connection and maintains common pin orientation across installations. A concealed manual override coded N9 allows emergency switching without exposing internal parts to contamination. The valve withstands operating pressures up to 350 bar, enabling use in high-pressure circuits such as presses or mobile machinery. Switching events can occur at rates up to 15 000 per hour, supporting fast cycling applications. An IP 65 protection type shields the energized parts against dust and water jets when the mating connector is fitted, improving field reliability. NBR sealing material is selected for compatibility with conventional mineral oils and for stable performance across typical temperature ranges. Together, these features enable precise, durable, and maintainable flow control in compact hydraulic manifolds.
