Still looking for 2 DIN valves, specifically made for AL80 tanks. Thanks!
There is no such thing as 'specifically made for AL80 tanks', although there are some that are commonly used on AL80s. A valve is a valve. The same valve will go on a Catalina tank of any size and pressure, or an old Walter Kidde, or a steel Faber tank. A disk suitable for the tank pressure is then put onto the valve..
What you need is the tank thread (here in Europe they are all by law M25x2). For the US you might have to look at what is stamped on the tank, however, most tanks are 3/4" UNF if I remember correctly, although in the past all sorts of threads have been used including taper threads, BSP, and NGS threads. So, providing the valves of kpdivers have the correct thread, then the valves would have screwed in and worked just fine on almost any tank. The burst disk then has to be opened, and the correct 3000psi disk inserted. Changing a burst disk is I think relatively common, and they could be changed at each hydro test.
Next time, just make sure you have the correct thread on the valve, everything else if 'fluff', and routinely changed, serviced etc.... Sorry I wasn't able to help, my tank valve is M25x2.
