The M-3SEW10U1X/420MG96N9K4/B20V is produced by Bosch Rexroth for the M-SEW Poppet Valves series and is intended for hydraulic automation tasks where electrically actuated flow control is required. It operates with a coil voltage of 96 V, matching DC supplies used in industrial cabinets. Because the voltage type is DC, polarity must be observed during installation. The voltage tolerance of ±10 % prevents malfunction when the incoming voltage drifts within that band. A power consumption of 30 W defines the electrical load that must be provided by the control system. Continuous energization is permitted because the duty cycle is rated at 100 %, avoiding the need for intermittent cooling periods. The high-power air-gap solenoid produces the magnetic force needed to shift the poppet under full pressure. A coil max surface temperature of 120 °C establishes the limit for safe thermal operation during extended use.
It uses a 3/2 directional function, giving three ports and two switching positions to start or stop flow in pressure circuits. An operating pressure capability of 420 bar allows deployment in high-pressure manifolds. Mineral oil is specified as the hydraulic fluid, ensuring compatibility with standard power units. A 2.0 mm throttle orifice labeled B20 limits flow to control actuator speed and reduce pressure spikes. Up to 15 000 switching cycles per hour at pressures not exceeding 350 bar support rapid repetition in servo-controlled equipment. A concealed manual override coded N9 permits local actuation while protecting the mechanism from accidental engagement. Connection is made through a DIN EN 175301-803 K4 plug, simplifying wiring in modular panels. The enclosure meets IP65, so dust ingress and water jets will not compromise operation. FKM seals marked V resist common hydraulic oils and high temperatures, maintaining leak-tight performance.
