The valve handle is 9' in the air, it is out of reach of accidential or curious shutoff. I'm confident I could get a PE stamp on it if I needed one. But that would be overkill to say the least. Now the tank is trivial to change. I have a pressure gauge co-located. Should the gauge fail or leak, I have a hand tightenable cap that can be installed in seconds cabletied at it's T. The ball valve has no moving parts and if it failed, it would fail in it's current position, open. I'm comfortable with this install. In the future (i.e. sale of home), should anyone have a problem with the valve, it's simple enough to remove. But a local home inspector (w/PE) here had no problems with my install, actually liked it and the way I had the tank, and pressure gauge in a conspicious location where the owner (me) could see both the tank install date written on the tank, and the current pressure. And since I've made it easy to replace the tank, I'm more likely to do it on a periodic basis.
