The M-3SEW6U3X/420MG24N9K4 valve is produced by Bosch Rexroth for the M-SEW Poppet Valves series. It serves as a solenoid-actuated shut-off element in hydraulic automation where positive sealing is required under high pressure. The component is built in size 6 to fit standardized subplate cavities, and it follows the ISO 4401-03-02-0-05 porting pattern so the body can mount directly on common CETOP 03 manifolds. The flow path handles up to 25 l/min, while the poppet withstands operating pressures as high as 420 bar to support compact yet powerful circuits. System fluid must be mineral oil, and the manufacturer specifies a cleanliness level of ISO 4406 20/18/15 to prevent premature wear. Back-pressure at the tank connection is permitted up to 100 bar, allowing use in return lines that see elevated counterpressures.
At the electrical end, the solenoid coil is wound for 24 VDC and draws 30 W during steady energization. A 100 % duty cycle allows continuous activation without thermal cycling, provided the coil surface does not exceed 120 °C. The winding is terminated through a DIN EN 175301-803 form K4 connector, and when the matching plug is fitted the enclosure reaches IP65 to block dust and low-pressure jets of water. The design supports a switching rate of 3600 cycles per hour at pressures above 350 bar, making it suitable for rapid on-off control. NBR seals resist typical mineral-based fluids, and the assembled valve weighs 1.5 kg, easing installation on compact manifolds.
