No Bleed Valve SPG?

[evsa]

I connected a high pressure gauge directly to a yoke valve. I used a brass high pressure quick release to connect the two and attached to a tank. The tank is under pressure. No bleed valve was part of the setup. This was understandably a mistake because now it is under pressure with no way to release the pressure. Any ideas?

Not sure what the set up looks like, but is there a fitting somewhere you can loosen slightly after closing the tank?

Preferably a low-pressure port plug on the reg, so you are not dealing with full tank pressure.

Thanks for your reply Pavao. I did try to slightly unscrew at different points (yoke valve screw) but it's pretty stuck.

Does anyone know if that black rubber piece on the edge of SPG is a bleed of some sort?

Unfortunately no low pressure plugs or ports on the set up, just the yoke valve connector (DIN with yoke adapter)

Could loosen the burst disc (will need to be replaced)...

I assumed you had a first-stage regulator on the tank. Sorry.
If you have attached a HP gauge directly to the tank valve output, you've got a problem.
So you have tank valve, yoke converter, DIN connector to an HP gauge? can you slighlty undo the yoke-DIN fitting with a big wrench? Quarter-turn at a time...
Since you "SPG" is apparently not a scuba SPG, I don't know what the blak plug is. A scuba SPG has no pressure in it, so no pressure relif port. ALl the presure is insde a bourdon tube.
Maybe a picure of your setup would help?

And wait for the entire tank to empty?
