The M-4SEW6D3X/420MG24N9K4/P valve is manufactured by Bosch Rexroth within the M-SEW Poppet Valves series. It functions as a 4/2 directional seat valve to shift hydraulic circuits in automation tasks. A maximum operating pressure of 420 bar allows the unit to work in high-pressure lines, while a maximum flow of 25 l/min matches medium-capacity actuators. The ISO 4401-03-02-0-05 porting pattern lets the body mount directly on size 03 subplates without adapters. The hydraulic passages are optimized for mineral oil, ensuring fluid compatibility with common industrial supplies. A built-in check valve insert blocks reverse flow and supports load holding when the poppet is de-energized. The tank port tolerates up to 100 bar so back-pressure in return lines does not impair switching. At 2.3 kg, the valve can be handled and installed by a single technician.
A high-power solenoid marked “M” drives the poppet, and the coil accepts a 24 VDC supply to integrate with standard machine control voltages. Continuous duty at 100 % allows the actuator to remain energized without overheating, and power consumption is 30 W under rated conditions. The coil surface temperature may reach 120 °C, a limit that defines permissible ambient and fluid temperatures. Electrical termination is provided by a DIN EN 175301-803 K4 connector, streamlining replacement in the field. An IP65 protection class seals the housing against dust ingress and low-pressure water jets so wash-down areas are permissible. A concealed manual override labeled N9 enables local shifting during commissioning or power loss without exposing moving parts. Together these electrical features complete the hydraulic functions described earlier and make the valve suitable for continuous service in automated systems.
