The M-3SEW6U3X/630MG205N9K4 poppet valve is produced by Bosch Rexroth for the M-SEW Poppet Valves series and is intended to switch hydraulic flow in automated machinery. It carries out a 3/2 U-symbol directional function so a single solenoid can alternately connect pressure and return lines. A maximum operating pressure of 630 bar lets the unit work in high-pressure power packs, while a flow rating of 25 l/min limits velocity through the ports to maintain stable actuator motion. The high-power air-gap solenoid delivers rapid force to the poppet for dependable shifting. A coil supply of 205 V DC combined with 30 W power consumption defines the electrical load on the control circuit. The coil surface may reach 120 °C, setting the insulation temperature class for continuous duty. An IP65 enclosure protects internal parts from dust and low-pressure water, and the 1.5 kg mass allows straightforward handling during manifold installation.
The valve uses a DIN 24340 Form A porting pattern so it bolts directly to common CETOP 03 sub-plates; the ISO 4401-03-02-0-05 and NFPA T3.5.1 R2-2002 D03 interfaces provide the same footprint for international compatibility. Connection to the wiring harness is made through a DIN EN 175301-803 K4 plug, enabling quick coil replacement in the field. Mineral oil is the approved hydraulic fluid to ensure seal longevity and consistent switching force. A concealed manual override designated N9 allows local actuation without exposing mechanical parts, supporting maintenance checks during commissioning. The T-port is rated for 100 bar back pressure, preventing return-line surges from forcing the poppet open. Together, these specifications allow the valve to deliver reliable on-off control inside compact hydraulic manifolds.
