Festo
173104
Solenoid valve MEBH-5/3B-1/8-P-S-B-230AC
The Festo 173104 is an electrical industrial component featuring a 5/3 pressurized valve function, a piston slide design structure, and a standard nominal flow rate of 400 l/min across a working pressure range of -0.9 to 10 bar. Built with a 17.8 mm width, 18 mm grid dimension, 5 mm nominal size, and soft sealing principle, this piloted unit utilizes external pilot air supply, mechanical spring reset, and features throttleable exhaust-air function with a reversible flow direction and freedom from overlap. Rated to IP65 protection class with c UL us recognition, the device includes detenting manual override with accessories, supports any assembly position, and requires a switching frequency of at least once a week for forced dynamisation.
