M-2SEW6P3X/420MG125N9K4/V

The M-2SEW6P3X/420MG125N9K4/V poppet valve is produced by Bosch Rexroth within the M-SEW Poppet Valves series. It is used to switch hydraulic flow paths in automation manifolds where leak-free sealing and high operating pressure are required. The valve follows the ISO 4401-03-02-0-05 port pattern, so it can be mounted directly on D03 subplates without adapters. A maximum operating pressure of 420 bar supports high-pressure circuits, while the maximum flow rating of 25 l/min defines the volume it can handle without excessive pressure drop. The built-in high-power air-gap solenoid supplies the force needed to shift the poppet against full system pressure. Coil energization is specified at 125 VDC, and the ±10 % voltage tolerance allows use with unregulated industrial power supplies. Continuous energization is possible because the duty cycle is 100 %, and electrical demand stays moderate with a power consumption of 30 W. Together these parameters support reliable, uninterrupted valve operation in hydraulic automation cells.

The valve tolerates 100 bar on the tank port, allowing it to discharge into back-pressurized return lines without functional loss. It can switch up to 3600 times per hour at pressures above 350 bar, so it suits fast-cycling actuators on presses or test stands. Wiring is completed through a DIN EN 175301-803 K4 connector, giving a standardized plug-in interface for machine harnesses. A concealed N9 manual override lets maintenance staff shift the poppet when electrical power is absent yet stays protected from inadvertent activation during normal service. The coil surface may reach 120 °C, a limit that guides enclosure ventilation and ambient temperature selection. An IP65 protection class shields internal components from dust ingress and low-pressure water jets, while FKM seals withstand common hydraulic oils and elevated fluid temperatures. The assembly weighs 1.5 kg, so it can be fitted onto compact manifolds without heavy supporting brackets, completing the functional data set for installation engineers.
