if you scroll to the third set of valves and look at the only one, is that a qev because it came up as a safety pop off valve, and if it is will i be abel to thread out the lever and replace it with my own pilot valve

Well that link just goes right to mcmaster.

I did however search for safety pop off valves and had a look at them.


And yes they are just relief valves, when the pressure gets too high they lift a bit and dump gas until the pressure falls to the correct level.

The lever is a manual test. It might also be a ring pull but for heavy duty versions it's a lever.

If you need to direct someone to a product on www.mcmaster.com, you have to give the catalog number.
