edit : reading more carefull, thats the check valve that is rated at 1800 psi, if it sees 1800 in the valve it will pop the check valve so the tank doesn’t explode

Yeah, I think I you mean so the gun doesn’t explode.
After looking again I noticed the 1800psi is on the top of the regulator valve.
It is a 3000psi tank.
