The M-3SED6CK1X/350CG24K4 poppet valve belongs to the M-SED Poppet Valves series and is produced by Bosch Rexroth for hydraulic automation circuits that require leak-tight shut-off and rapid switching. It performs a 3/2 normally closed function, so flow is blocked in the de-energized state and opened when the coil is powered. The unit handles system pressures up to 350 bar to suit medium and high-pressure manifolds, while a maximum flow rate of 25 l/min supports compact actuators and pilot lines. A standardized ISO 4401-03-02-0-05 porting pattern simplifies stack mounting with sub-plates and sandwich modules. The solenoid coil operates on 24 V DC, and a ±10 % voltage window prevents mis-trips from supply variation. Continuous energization is permitted because the duty cycle is 100 %, and thermal load remains within limits at a power draw of 30 W.
Electrical connection is made through the EN 175301-803 type K4 plug, and when the matching plug is fitted the housing attains an IP65 rating that shields the coil from dust and low-pressure water jets. Switching tasks can be repeated up to 15 000 times per hour at or below 350 bar, letting the valve serve in high-cycle control loops. There is no manual override, so actuation is restricted to electrical commands, which prevents unintended operation in guarded machinery. NBR seals provide compatibility with common hydraulic oils and maintain internal tightness over the full pressure range. Installation uses two M5 × 50 screws according to ISO 4762, tightened to 8 N·m to secure the body without distorting the sub-plate. The assembled valve weighs 1.5 kg, allowing straightforward handling during panel or manifold assembly.
