Hello, I'm looking for a ball valve which has two switchable outputs. Basically something that has one inlet, and three possible positions, off, port a and port b. 1/2" ID would be perfect. I've seen three way ball valves out there, but the cheap ones are about $50. I was thinking of just putting two regular brass ball valves on a T splitter, but if anyone knows of a better solution, please let me know.
