I am curious how may people have had problems with Psc orbital valves. My car handled very bad( bypassing valve?). I called Psc for technical help and they gave me very little advice. So I called one of their competitors and they were very helpful over the phone. So I bought an orbital valve from them and now my buggy handles perfect( for full hydro).The whole deal kinda sucks. I am guessing Psc valves are made to name brand specs and quality(charlynn/damnfoss/eaton)
