SBD valves? Need help wiring

Anybody heard of these? Bought some off a member here and now I can't wire them cause they have a 3 prong? I run all smc right now so I really don't know how to use these help would be good.

if you're looking at the prongs straight on left and right is your 12v/ground. polarity doesn't matter. if you want the valve to ground to chassis (cleaner install) jump the l/r ground to the bottom prong.

So the left is 12 v and the right is the ground? What happens to the top middle prong?are these valves anygood?

never heard of them. all your answers are in the post above. if you don't want to ground through the vlave then you don't use the bottom prong.
