The Festo OS-1 8-B pneumatic three-way valve with OR logic gate is a compact, air-operated valve that manages flow between three ports in automation systems. With built-in OR logic, either of two input signals can drive the output, enabling parallel control of actuators or downstream valves without a second control line. As part of the Festo OS-1 8-B lineup, this valve is designed for integration into compact pneumatic circuits where reliable signal combining and space efficiency matter.
