The M-3SEW6U3X/420MG24N9K4/B20V poppet valve is manufactured by Bosch Rexroth for the M-SEW Poppet Valves series and is used to switch hydraulic flow on machinery. It withstands operating pressures up to 420 bar so it can be installed in high-pressure circuits, and it passes up to 25 l/min to accommodate moderate flow demands. The ISO 4401-03-02-0-05 porting pattern lets the body bolt directly to common subplates, minimizing plumbing. A high-power solenoid marked M drives the poppet, and the coil runs on 24 V DC within a ±10 % voltage window to cope with supply variation. Continuous energization is allowed because the duty cycle is 100 %, while electrical draw is limited to 30 W to reduce panel loading.
The enclosure carries an IP65 rating so it resists dust and low-pressure water jets encountered in plant environments. A DIN EN 175301-803 K4 connector provides the electrical interface, and a concealed manual override labelled N9 lets technicians shift the valve without power. Coil surface temperature may reach 120 °C and must be considered for adjacent components. FKM seals are fitted to handle typical hydraulic oils, and the required fluid cleanliness is ISO 4406 20/18/15 to protect internal parts. A 2.0 mm throttle orifice identified as B20 meters flow during actuation, and the assembled valve weighs 1.5 kg for easy manifold handling.
