The M-3SEW10U1X/630MG24N9K4/V is a valve manufactured by Bosch Rexroth for the M-SEW Poppet Valves series and is intended for high-pressure hydraulic automation circuits. It provides a 3/2 directional function identified by symbol U, allowing reliable switching between supply, outlet, and tank lines. A continuous duty cycle of 100 percent keeps the solenoid energized without enforced cool-down periods, while power consumption is limited to 30 W to manage panel loading. The coil accepts a nominal voltage of 24 V DC, and a ±10 percent voltage tolerance maintains actuation force under fluctuating supply conditions. Electrical termination is through a DIN EN 175301-803 K4 connector, simplifying field replacement. The coil surface temperature limit of 120 °C safeguards winding insulation during sustained operation, and an operating pressure rating of 630 bar makes the unit suitable for heavy-duty clamping and pressing equipment.


Hydraulic fluid can range from −20 °C to 80 °C when FKM seals are specified, so the valve remains leak-tight across common industrial oil temperatures. An ambient temperature ceiling of 50 °C protects exterior elastomers and coil resin in crowded manifolds. The ingress protection level of IP65 blocks dust and low-pressure water jets, allowing installation on exposed machinery. A concealed manual override coded N9 permits local shifting during commissioning or power loss without increasing envelope size. System cleanliness must meet ISO 4406 class 20/18/15 to reduce poppet wear, and the minimum fluid viscosity of 2.8 mm²/s ensures adequate film strength across the metering edges. Seal material is FKM, offering resistance to mineral oils and many synthetic fluids. Together these limits and features provide predictable service life when the valve is mounted in modern hydraulic power units.
