The M-3SEW6U3X/420MG110N9K4/B12 CSA valve belongs to the M-SEW Poppet Valves series and is produced by Bosch Rexroth for hydraulic automation tasks that require leak-free directional control. It is built in size 6, follows the ISO 4401-03-02-0-05 porting pattern, and withstands operating pressures up to 420 bar. The poppet is limited by a 1.2 mm throttle orifice to stabilize flow, and the unit passes as much as 25 l/min while keeping T-port back pressure below 100 bar. System fluid must meet ISO 4406 cleanliness class 20/18/15 to avoid seat wear and ensure reliable response.
The solenoid coil is rated for 110 V DC with a ±10 % voltage window, draws 30 W, and can run continuously at a 100 % duty cycle; under these conditions the coil surface may reach 120 °C. Wiring is completed through a DIN EN 175301-803 type K4 connector, and the housing attains IP65 protection against dust and water jets. A concealed N9 manual override permits local shifting during power loss, and the assembly weighs 1.5 kg for straightforward installation.
