The M-3SEW6U3X/420MG24N9K4 CSA valve is manufactured by Bosch Rexroth within the M-SEW Poppet Valves series. As a 3/2 directional seat valve, it directs hydraulic flow for automation tasks that require leak-free shutoff. Nominal size 6 provides a compact mounting footprint for modular stacking. The body follows the ISO 4401-03-02-0-05 porting pattern so it aligns with common subplates. A high-power air-gap solenoid actuates the poppet to ensure positive switching under high pressure. The coil operates at 24 V DC, draws 30 W, and can stay energized continuously thanks to a 100 percent duty cycle. A DIN EN 175301-803 K4 connector simplifies wiring and supports quick field replacement. An IP65 housing rating keeps dust and water jets from compromising the coil and internal wiring.

Maximum operating pressure of 420 bar permits use in high-pressure circuits such as presses and lifting equipment. Flow capacity to 25 L/min matches small to medium actuator requirements without excessive pressure loss. Tank port pressure is limited to 100 bar, so return line components must be selected accordingly. The cleanliness class of ISO 4406 20/18/15 indicates the oil filtration level needed to protect the poppet sealing surfaces. NBR seals are fitted to provide compatibility with common mineral hydraulic oils. A concealed manual override labeled N9 allows emergency actuation while preventing accidental engagement during normal operation. Unit weight of 1.5 kg aids installation on manifold blocks without additional support brackets.
