All, Product question. Looking for a butterfly valve with built-in tamper switch (or add-on) that produces a supervisory signal after two-turns of the handle from the CLOSED position. I can find lots of butterfly valve that do this from the OPEN position.
Military project/specifications. I don't want to use OS&Ys all over the place.
