enable control from multiple sources in your air systems. These compact aluminum alloy valves allow flow from either of two inlets to a common outlet, preventing cross-flow. Ideal for simple logic circuits, interlocks, or remote operation (M5-G1/2″ ports). Ensures reliable selection of the higher-pressure input.
