The M-3SEW6U3X/420MG96N9K4 poppet valve is manufactured by Bosch Rexroth and belongs to the M-SEW Poppet Valves series. It directs oil between three ports and two positions, a 3/2 directional seat arrangement that seals reliably under load. The unit works in circuits up to 420 bar, so it can handle high-pressure actuators without external pressure reducers. A peak flow of 25 l/min lets it serve medium-capacity lines while keeping response time short. The body fits an ISO 4401-03-02-0-05 (D03) interface, allowing direct mounting on common manifold plates. Actuation is provided by a high-power air-gap solenoid with a detachable coil, giving fast shifting and simple replacement. The coil is energized with 96 V DC, and the ±10 % voltage window maintains force when supply varies. Continuous duty at 100 % makes the valve suitable for uninterrupted cycles in presses or servo loops.
Power draw is limited to 30 W, which keeps panel transformers small and reduces heat in compact manifolds. When coupled with the mating connector, the housing meets IP65, so dust and water jets cannot reach live parts. Electrical termination follows DIN EN 175301-803 form K4, providing a keyed plug that installs without tools. A concealed manual override identified by code N9 lets technicians shift the poppet during commissioning while preventing accidental use in service. Tank port pressure is permitted up to 100 bar, allowing back-pressure circuits without damaging the seat. The hydraulic system must supply oil cleaner than ISO 4406 20/18/15 to avoid leakage wear. Coil surface temperature may rise to 120 °C, so clearance must be provided for heat dissipation. The assembly weighs 1.5 kg, enabling easy handling during manifold installation.
