The M-3SEW6C3X/420MG24K72L valve is produced by Bosch Rexroth as part of the M-SEW Poppet Valves series. It serves as a solenoid-actuated poppet element that switches flow paths in compact hydraulic manifolds. The coil operates on a nominal 24 V DC supply, and the circuit tolerates ±10 % voltage variation so brief line fluctuations do not interrupt actuation. Electrical demand is 30 W, simplifying power distribution in multi-valve assemblies. A 100 % duty cycle allows the solenoid to remain energized continuously, while the coil surface can reach 120 °C without degrading insulation, which supports rapid cycling. An IP65 housing shields the electrical parts from dust and water jets, enabling placement near wash-down zones. Designers may install the unit in any orientation, and the ISO 4401-03-02-0-05 porting pattern speeds manifold integration. The valve weighs 1.5 kg, so a single technician can position and secure it during maintenance or retrofit work.
Hydraulic performance addresses high-pressure automation tasks. The poppet structure safely carries 420 bar on ports P, A, and B, making it suitable for direct control of cylinders that demand elevated clamping or pressing forces. Backpressure at port T may reach 100 bar, protecting return lines when flow is restricted. Internal passages accommodate up to 25 l/min, matching the delivery of small and medium pumps used in machine tools and handling systems. Stable switching is retained with hydraulic fluid between –30 °C and 80 °C, so the valve functions during cold starts and under elevated oil temperatures typical of continuous service. Ambient operating limits from –30 °C to 50 °C permit use in outdoor equipment or unconditioned factories without supplemental enclosures. These pressure, flow, and temperature capabilities let the valve maintain leak-tight closure and quick response across the specified environmental range.
