The M-3SEW6C3X/420MG205N9K4 valve belongs to the M-SEW Poppet Valves series and is produced by Bosch Rexroth for directional control in hydraulic automation. It is built in size 6 and conforms to mounting pattern ISO 4401-03-02-0-05, allowing direct installation on standard subplates. A maximum operating pressure of 420 bar on ports P, A, and B enables use in high-pressure circuits, while peak flow reaches 25 l/min for moderate volume applications. The flow path follows symbol C in a 3/2 configuration, so the poppet shifts fluid between two service ports and the supply. System oil must meet cleanliness class ISO 4406 20/18/15, and a concealed manual override lets technicians shift the valve during commissioning.
The solenoid assembly operates on 205 V DC and draws 30 W, so electrical sizing is straightforward. Continuous service is supported by a 100 % duty cycle, and the coil surface may reach 120 °C without exceeding limits. Connection is made through a DIN EN 175301-803 plug, and the housing meets IP65, guarding against dust and low-pressure water jets. The valve works with mineral oil hydraulic fluid, and NBR seals contain the media under both dynamic and static conditions. Tank port pressure is permitted up to 100 bar, ensuring safe return line operation. These electrical and material features complement the hydraulic ratings introduced earlier and complete the operating profile of the device.
