Code requirements for ball valves being used for fuels in Quebec dictate that they be either certified API607 valves, or ULC 842 certified with an additional requirement that they be rated to a 1000 deg F melting point. I am unable to find any information that states this requirement for melting point, all information just indicates a temperature/pressure relationship for these valves. Any idea where this 1000 deg F melting point originates from? Is this a requirement for API607 valves or ULC 842 testing procedures?
