The M-4SEW6D3X/420MG24N9K4QMAG24 valve belongs to the M-SEW Poppet Valves series and is manufactured by Bosch Rexroth. It is built as a 4/2 directional seat valve, identified by symbol D, and is intended to route hydraulic flow to actuators in automated machinery. A nominal size of 6 allows the unit to fit compact manifolds, while the ISO 4401-03-02-0-05 porting pattern ensures straightforward subplate mounting. The assembly handles operating pressures up to 420 bar so it can be installed in high-pressure circuits, and it passes up to 25 l/min to support medium-flow systems. When system pressure exceeds 350 bar the solenoid can cycle up to 3600 times per hour, enabling rapid sequence work. Continuous energization is permitted because the duty cycle is rated at 100 percent, preventing thermal limitations during long production shifts.
For electrical integration the coil is designed for 24 V DC and draws 30 W, letting panel designers size power supplies and conductors accurately. A DIN EN 175301-803 plug in the K4 configuration provides the connection interface and, together with an IP65 housing, protects internal parts from dust and low-pressure water jets. The permissible coil surface temperature reaches 120 °C, establishing the thermal ceiling during prolonged activation. Return-line stress is limited because the tank port may see no more than 100 bar. Spool position feedback is available through the QMAG24 monitor in position “a”, allowing controllers to verify whether the valve has shifted. Overall mass is 2.3 kg, so installation can be managed without lifting aids. These attributes combine to deliver a poppet valve suited for repetitive, high-pressure motion tasks in hydraulic automation.
