The M-3SEW6U3X/630MG24N9K4/V valve is manufactured by Bosch Rexroth within the M-SEW Poppet Valves series for hydraulic automation where safe flow shut-off is required. It employs a 3/2 directional function (symbol U) to control supply, actuator, and return lines. The assembly tolerates a maximum operating pressure of 630 bar and passes up to 25 l/min, making it suitable for medium-capacity circuits. A mounting pattern conforming to ISO 4401-03-02-0-05 (D03) allows direct installation on common subplates, and any installation position is acceptable, simplifying manifold design. The tank port withstands 100 bar so back-pressure does not compromise service life. FKM seals resist mineral oils and elevated temperatures, while an IP65 housing prevents dust ingress and water jet penetration. The valve weighs 1.5 kg, easing handling during assembly and maintenance.

The solenoid coil is rated for 24 V DC and accepts a ±10 % voltage swing to remain functional with typical industrial supplies. Continuous energization is permitted because the duty cycle is 100 %, and electrical power demand is limited to 30 W, reducing heat generation inside control enclosures. The coil surface may reach 120 °C, so nearby components must be positioned accordingly. Wiring is completed through a DIN EN 175301-803 K4 connector that provides quick disconnection during service. Hydraulic media must be maintained at ISO 4406 cleanliness class 20/18/15 or better to avoid poppet wear and leakage.
