BlackFlow Valve Broken?

My backflo valve seems to need replacement, but not complete sure if I need to replace the whole valve or can just replace the handle assembly.

When I turn either one of the handles, they don't seem to do anything. I can turn them in both directions endlessly.

Secondly, forget for a second that they may be broken, how are these supposed to be set? That the fist one (nearer water supply) supposed to be open or closed? Are they both supposed to be open?

Not sure how it is supposed to work.

When you try to turn the water off you need to make sure that the handles are side to side not up and down. It sounds like the handles are just bad. You also might try to take the handles off the valve and just use a cresent wrench and turn the valve off, once again make sure that the little brass bolt that the handle bolts to is up and down that will guarntee that the water is off. I hope this helps.
