The M-3SEW6U3X/420MG110N9K4/B08 is a poppet valve in the M-SEW Poppet Valves series manufactured by Bosch Rexroth for hydraulic automation tasks that require dependable on/off control. Its 3/2 directional seat design provides one pressure, one work, and one tank line, giving simple switching for single-acting cylinders. Nominal size 6 sets the flow cross-section so the valve fits compact CETOP 03 manifolds. The ISO porting pattern 4401-03-02-0-05 aligns the mounting holes with standard subplates, streamlining replacement work. Three main ports make system plumbing straightforward by eliminating external jumpers. A 110 V DC coil energizes the solenoid directly from DC panels, while a 100 percent duty cycle allows the coil to stay powered continuously without thermal stress. The DIN EN 175301-803 form K4 plug provides a sealed electrical interface, and 30 W power consumption defines the load the control supply must deliver.
A concealed manual override identified by code N9 lets technicians shift the valve mechanically during commissioning or power loss. The assembly tolerates up to 420 bar operating pressure, enabling use in high-pressure presses and molding machines. A maximum flow of 25 l/min caps actuator speed and helps maintain stable pressure control. Port T withstands 100 bar so return-line back-pressure will not disturb the seat. A built-in 0.8 mm throttle orifice softens flow during switching and limits pressure spikes. IP65 protection keeps dust and water jets out of the coil enclosure for reliable service on the factory floor. NBR seals are compatible with standard mineral oils, maintaining leak-tight operation across typical temperature ranges. The valve weighs 1.5 kg, allowing one-person installation on manifold plates and minimizing added mass in mobile equipment.
