The M-3SEW10C1X/420MG96N9K4/B20 belongs to the M-SEW Poppet Valves series from Bosch Rexroth and serves as a direct-operated seat valve for hydraulic automation. Its 3/2 directional function with Symbol C lets a circuit connect or block flow between three main ports, which supports pressure hold and release tasks. A rated pressure of 420 bar allows the valve to work in high-pressure manifolds without derating. Actuation is handled by a high-power air-gap solenoid that provides strong shifting force, while a 96 V DC coil matches medium-voltage DC control networks. The direct-operated design moves the poppet without pilot flow, giving fast response for precise machine cycles.
Connection to system wiring is made through a DIN EN 175301-803 K4 plug, so installation follows a common industrial connector pattern. A concealed manual override coded N9 is available for local operation when electrical power is absent, yet the recessed design prevents accidental activation. NBR sealing is chosen for compatibility with mineral-oil fluid, the medium specified for this valve, and it resists swelling during continuous duty. A 2.0 mm throttle orifice labeled B20 limits inrush flow to reduce shock when the valve opens. There is no internal check-valve insert, so reverse flow blocking must be handled elsewhere, and no position switch is provided, meaning the control system will not receive electrical feedback about spool state.
