M-4SEW10D1X/630MG24N9K4/V

The M-4SEW10D1X/630MG24N9K4/V valve belongs to the M-SEW Poppet Valves series and is manufactured by Bosch Rexroth. It is a directional seat valve intended for hydraulic automation where positive shut-off of flow is required. Direct operated actuation eliminates pilot stages and shortens response time. A high-power air-gap DC solenoid supplies the force needed to shift the seat, and the coil is detachable so service technicians can replace the coil without opening the hydraulic envelope. The solenoid is rated for 24 V DC, allowing direct connection to common machine controllers. Electrical connection is achieved through a DIN EN 175301-803 form K4 plug, which provides a sealed and standardized interface. The concealed manual override identified as N9 lets operators move the valve during commissioning or power loss while protecting the button from accidental use. Flow paths correspond to spool symbol D, giving a predefined switching pattern suited to typical four-way circuits.

The valve handles system pressures up to 630 bar, enabling use in high-pressure presses and forming machines. It is specified for mineral-oil media, so reservoirs filled with ISO VG hydraulic oils can be used without modification. FKM sealing is supplied, providing resistance to elevated temperatures and aggressive additives found in modern fluids. Four main ports offer dedicated connections for pressure, tank, and two actuator lines, supporting standard directional control layouts. No check-valve insert is fitted, meaning backflow prevention must be arranged externally when required. The design also omits a throttle insert, so any flow limiting must be performed with separate orifices in the circuit. There is no position switch, therefore the controller will not receive electrical confirmation of spool state and must rely on pressure or flow feedback if monitoring is needed. These characteristics define the installation tasks and circuit functions that must surround the M-4SEW10D1X/630MG24N9K4/V valve.
