M-3SEW10C1X/630MG205N9K4

The M-3SEW10C1X/630MG205N9K4 poppet valve belongs to the M-SEW Poppet Valves series and is produced by Bosch Rexroth for hydraulic automation that requires leak-free shutoff under high pressure. It uses a direct-operated seat valve design so the poppet lifts directly from the seat for rapid switching. The assembly is rated for an operating pressure of 630 bar, letting it control cylinders or motors in very high-pressure circuits. Three main ports accommodate the usual P, A, and T lines in manifold blocks. The valve handles standard mineral oil, simplifying fluid selection in industrial power units. It can be mounted in any installation position, easing manifold layout, and a concealed manual override lets service personnel shift the poppet without exposing moving parts. During energized operation the solenoid draws 30 W of power, information needed when sizing the electrical supply.

The coil is specified for 205 V DC, and a voltage tolerance of ±10 % keeps switching performance consistent when the supply fluctuates. A duty cycle of 100 % allows continuous energization without exceeding thermal limits. Protection class IP65 is achieved when the mating connector is fitted, preventing dust and water jets from reaching the electrical cavity. The valve body may reach a surface temperature of 120 °C, so nearby components must tolerate that heat. The required fluid cleanliness is ISO 4406 class 20/18/15, reducing the risk of poppet or seat damage from particulates. These parameters enable stable, leak-free operation in demanding hydraulic machinery.
