The M-3SED6CK1X/350CG125N9K4QMAG24 valve belongs to the M-SED Poppet Valves series and is produced by Bosch Rexroth for hydraulic automation where reliable on-off flow control is required. The unit employs a wet-pin DC solenoid to keep the coil surrounded by fluid, improving heat dissipation and minimizing corrosion. Its coil draws 30 W so the poppet can be shifted quickly without excessive energy use. A 100 % duty cycle allows the solenoid to remain energized continuously during long machine cycles. The coil may reach 150 °C without damage, letting the assembly work in hot oil reservoirs. Supply voltage may fluctuate by ±10 % while maintaining stable actuation. A plug built to DIN EN 175301-803 standardizes the electrical connection for easy wiring. The housing carries an IP65 rating, protecting internal parts from dust and water sprays. A concealed manual override labeled N9 lets maintenance staff move the poppet during commissioning or power loss.
The steel body tolerates operating pressures up to 350 bar, allowing integration into high-pressure presses and clamping circuits. Three main ports enable two-position, three-way control that can direct flow or block it as required. When the poppet is closed the design is leak-free so downstream actuators hold position without external check valves. A maximum switching frequency of 15 000 cycles per hour matches fast indexing tasks on automated lines. Hydraulic cleanliness must be held to ISO 4406 code 20/18/15 to avoid premature seat wear. NBR seals handle common mineral oils and keep the valve tight across normal service temperatures. An integrated QMAG24 sensor reports poppet position to machine controllers, supporting diagnostics and confirming each switching event.
