The M-3SEW10U1X/420MG96N9K4/B12 poppet valve belongs to the M-SEW Poppet Valves series and is manufactured by Bosch Rexroth for hydraulic automation tasks. It implements a 3/2 directional function identified by symbol U, allowing it to switch flow between three main ports while venting or blocking as required. The valve is rated for 420 bar operating pressure, so it can be installed in high-pressure circuits that use mineral oil as the working fluid. A high-power air-gap solenoid actuates the poppet and is supplied with 96 V DC within a ±10 % tolerance, ensuring consistent performance on networks with limited voltage stability. Continuous energization is permissible because the coil supports a 100 % duty cycle, enabling rapid cycling without overheating.
When fitted with its mating connector, the electrical interface follows DIN EN 175301-803 pattern K4 and provides IP65 protection against dust and low-pressure water jets. The concealed N9 manual override lets technicians shift the poppet during commissioning or power loss without exposing moving parts. Maximum coil surface temperature is limited to 120 °C, so cabinet ventilation must maintain this threshold during sustained operation. No position switch is installed, meaning external sensors are required if feedback is needed. A factory-drilled 1.2 mm throttle orifice labeled B12 moderates pilot flow to damp pressure shocks while the valve operates in continuous service.
