20 lb propane tank pressure relief valve. Internal Pressure Relief Valve. Most propane tanks in residential and commercial service have internal safety relief valves. The reason for an internal valve as opposed to an external pressure relief valve is it presents less of an obstruction when moving the tank.
Internal relief valves are generally placed near the end of the propane tank on above ground containers. External Pressure Relief. Standard DOT 20 propane tanks have a pressure relief valve rated at 250 PSI.
The actual pressure at which the valve will release is dependant on many factors including age of the tankvalve how much propane is in the tank and conditions outside the tank itself. The following are vapor pressures of propane at various temperatures. 70 F 96 PSI.
For example a standard 20-pound propane tank at 70 degrees will have 145 psi internal pressure. That same tank on a 100-degree day will have 172 psi of pressure. Propane pressure levels exceeding 200 psi are likely to trigger a release from the safety relief valve commonly installed on propane storage tanks.

The typical LPG pressure relief valve setting is 2585 kPa or 375 PSIG. So the propane tank max pressure would never actually go above this as the valve would open and lets some gas escape limiting the LPG pressure inside the tank and never even approaching the propane tank max pressure rating limit.
