Can't get the valves off my steel tanks

Issue resolved. Found a guy with a "cylinder vise". Good to go.

Yeah so find yourselves a piece of inserted conveyor rubber curve it in half and bolt it to a wall

Then slip your tank in

A lot of talk here about ways to get valves out of cylinders and very little talk about making sure the pressure has been released first.

Just make sure you confirm there's no pressure in the cylinder before you take a 6ft wrench to the valve. It's bloody dangerous and the consequences are horrible, I've seen/investigated a few near death injuries.

Open the cylinder valve
Blow some air in with an airgun
Listen to hear the air escape again.

If no air escapes, no air went in. This indicates a potential blockage or valve issue and means you can't confirm the cylinder is empty. Take it to a hydro shop, they'll have the right tools/processes to sort it out.

I know everyone posting here is a highly trained technical expert and the above checks are implied but anyone at home could be reading... figured it was a good place to drop a note.

Yes we assume that most people are using their brain. Unfortunately that can not be assumed.

If after you crack it free, and it doesn't get looser, its either seized threads, or pressurized.
Or some other reason I haven't yet thought of.
Either way use your brain.

If you put 1000psi or so in the cylinders and then just open the valve and let it all drain the valve will get super cold and make it easier some times.
