Product Overview
The Rexroth M-4SEW10D16/420MG24N9K4 (Material Number R900087926) is a direct-operated, solenoid-actuated directional spool valve from the proven 4SEW series, size NG10 (CETOP 5 / ISO 4401-05). It controls the start, stop, and direction of hydraulic fluid flow in industrial power circuits, functioning as the pilot or main control stage in systems requiring reliable directional switching. The valve features a 4-way, 3-position spool configuration with a “D” type center condition (closed center), a nominal flow capacity of 16 L/min, and a spring-centered, wet-pin AC solenoid rated for 420 V at 50/60 Hz with a nominal power consumption of 24 W. The designation “MG24” identifies the solenoid variant with integrated manual override, while “N9” denotes the standard NBR (nitrile) seal package suitable for mineral oil-based hydraulic fluids. With a maximum operating pressure of 350 bar on the P, A, and B ports and 210 bar on the T port, this valve is engineered for high-pressure industrial duty and is fully interchangeable with original Rexroth mounting and connection interfaces.
