M-3SEW6U3X/630MG96N9K4/PV

The M-3SEW6U3X/630MG96N9K4/PV valve belongs to the M-SEW Poppet Valves series and is produced by Bosch Rexroth for hydraulic automation tasks that require leak-tight shut-off and rapid switching. As a 3/2 seat valve, it directs flow between pressure, actuator, and tank lines with minimal internal leakage, while the built-in check function allows free flow from port P to port A so return flow is unrestricted during switching cycles. The cartridge supports a maximum operating pressure of 630 bar, enabling use in high-pressure circuits such as clamping or press systems, and tolerates up to 100 bar on the tank port so back-pressure does not affect closure reliability. A maximum flow of 25 l/min matches medium-size actuator demands, and a switching frequency of 3600 cycles per hour above 350 bar lets the valve follow fast control commands. The coil is rated at 96 V DC and draws 30 W, providing stable magnetic force for full poppet travel under continuous duty because the solenoid is specified for a 100 % duty cycle.

The enclosure uses a DIN EN 175301-803 plug so wiring can be completed with standard industrial connectors, and a concealed manual override allows operators to shift the poppet mechanically for setup or fault clearing without energizing the coil. During continuous energization the coil surface may rise to 120 °C, which sets the limit for surrounding component materials and dictates spacing for thermal safety. An IP65 protection class protects internal components against dust and water sprayed from any direction, enabling installation on exposed machine frames. The valve bolts to manifolds through the ISO 4401-03-02-0-05 interface; this unified footprint keeps porting consistent across brands and eases service swaps. FKM seal material resists mineral oils, synthetic esters, and elevated temperature shock, lowering the risk of leakage over long duty cycles. With a weight of 1.5 kg the assembly can be lifted without special tools, reducing maintenance downtime while maintaining rigidity in the manifold stack.
