The M-4SEW6D3X/420MG24N9K4 poppet valve is built by Bosch Rexroth within the M-SEW Poppet Valves series for hydraulic automation circuits that need dependable direction control. It is a 4/2 directional seat valve in size 6 and follows porting pattern ISO 4401-03-02-0-05 to fit common subplates. The coil is energized at a nominal 24 V DC, draws 30 W, and tolerates voltage deviations of ±10 %. A DIN EN 175301-803 K4 connector provides the electrical interface, while a 100 % duty cycle permits continuous activation. The hydraulic section handles a maximum flow of 25 l/min and sustains 420 bar on ports P, A, and B, allowing the component to function in high-pressure supply lines.
Environmental ratings secure reliable performance once installed. The housing achieves protection class IP65 when the plug is properly fastened, and NBR seals are used to prevent external leakage. System fluid cleanliness is limited to ISO 4406 class 20/18/15, and tank port T must not exceed 100 bar to stay within design limits. The coil surface can reach 120 °C during extended operation, so ventilation or heat sinking may be required. Overall mass is 2.3 kg, enabling installation without heavy lifting gear. These characteristics support the valve’s role in hydraulic machines that demand high switching reliability under continuous electrical and hydraulic load.
