The TV-101-A is a Type I valve that has been verified as the one that does not work.
I called Peca today and they do not make a Type II valve and never have, and are in the process of discontinuing the TV-101-A.
The metal trigger valve is just to expensive compared to the plastic ones.
The TV-101-A is designed to screw on to the stem of the can and puncture it. You do not want to puncture the Colman can and the Colman can has no threads.
Without question, the TV-101-A Peca valve is the very same valve that Usher was using to produce the PowerMax trigger valve. Sure, it will not work on the PowerMax cans in its original stock form ( even if you can find it), and this is why Usher was having them modified. Whether or not he was doing the modifications himself or having it done by a local machine shop...I don't know.
