RE: Powermax Trigger Valve -- New Source
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.
