The M-3SEW6C3X/420MG125N9K4/V poppet valve belongs to the M-SEW Poppet Valves series manufactured by Bosch Rexroth. It is intended to switch hydraulic flow in automation circuits that require tight sealing and rapid actuation. The valve uses a 3/2 seat configuration identified as symbol C, allowing one service line to be connected or blocked relative to pressure and tank ports. Size 6 dimensions fit subplates that follow the ISO 4401-03-02-0-05 pattern. A high-power air-gap solenoid rated at 125 V DC drives the poppet and draws 30 W when energized. Continuous operation is possible because the design supports a 100 percent duty cycle. Electrical power is supplied through a DIN EN 175301-803 K4 connector, and a concealed N9 manual override lets personnel shift the poppet without energizing the coil.

The hydraulic section withstands 420 bar on pressure ports and 100 bar on the tank port, making the unit suitable for high-pressure manifolds. Maximum flow is 25 l/min, matching the passage area provided by the size 6 body. FKM seals resist common industrial fluids and separate the hydraulic cavity from the coil chamber. When the mating connector is fitted, the assembly achieves an IP65 protection class to exclude dust and water jets. Coil surface temperature can reach 120 °C during prolonged duty, remaining within the winding’s insulation limits. Overall weight is 1.5 kg, keeping manifold loading low and simplifying handling during installation.
