The M-3SEW6U3X/420MG24N9K4/B12 belongs to the M-SEW Poppet Valves series from Bosch Rexroth and serves as a 3/2 directional seat valve for hydraulic automation where leak-tight shutoff is required. A nominal size of 6 keeps the envelope small while still matching ISO 4401-03-02-0-05 mounting patterns, so the unit drops onto common subplates without adapter blocks. The flow path includes a 1.2 mm throttle orifice that limits surges and stabilizes actuator movement, and a design flow capability of 25 l/min supports moderate circuit demands. Continuous service at pressures up to 420 bar allows the component to operate on high-pressure pump groups used in presses or clamping systems. NBR seals resist standard mineral oils and simplify maintenance inventories, and the valve can be installed in any orientation to ease manifold layout during machine design.

An electrical coil rated at 24 V DC with a ±10 % voltage window permits direct connection to PLC output cards, while 30 W power consumption minimizes panel heat. A 100 % duty cycle lets the solenoid remain energized for indefinite periods when position holding is necessary. The DIN EN 175301-803 K4 connector provides quick wiring and allows field replacement without tools. A concealed manual override identified by code N9 offers local actuation during commissioning but prevents accidental shifts in service. The housing meets IP65, protecting the core from dust and low-pressure water jets so it can be mounted on open power units. At 1.5 kg, the valve is light enough for direct manifold mounting without additional support.
