The M-4SED10Y1X/350CG24N9K4 poppet valve is produced by Bosch Rexroth as part of the M-SED Poppet Valves series. It directs hydraulic flow in automation circuits by shifting between four ports and two positions, a 4/2 directional function that suits actuator control tasks. With size 10 and a standardized ISO 4401-05-04-0-05 porting pattern, it mounts interchangeably on common sub-plates. The solenoid accepts a nominal 24 V DC supply, and its coil can tolerate ±10 percent voltage variation while drawing 30 W during energized periods. Because the duty cycle is 100 percent, the coil may remain powered without scheduled cool-down intervals. A concealed manual override allows local actuation during commissioning or power loss, and an IP65 ingress rating protects internal parts against dust and low-pressure water jets encountered inside machinery bays.
The hydraulic section withstands operating pressures up to 350 bar while still opening reliably from 8 bar, delivering up to 40 liters per minute through the poppet bore. When driven by a matched amplifier the solenoid can switch as often as 15 000 cycles per hour, so the valve fits high-throughput sequences where rapid response is critical to machine takt time. Coil insulation endures temperatures as high as 150 °C, enabling continuous service in warm manifolds without premature aging of the winding varnish. NBR seals contain mineral oil fluids and resist wear under the stated pressure limits, maintaining tight shut-off across millions of strokes. During installation the body is secured with screws tightened to 12.5 Nm, preventing plate distortion and leakage at the gasket face, and the resulting assembly ensures stable flow characteristics throughout extended production shifts.
