Yes,
usually triple-offset metal seated valves are inherently fire-safe (in particular when they have graphite and/or ceramic fiber only in their "soft parts", without any PTFE, rubber or other polymers) and fire-tested (according to API 607 or similar standards).
For more information about this type of valves, take a look at the websites mentionen within Thread408-126483 and Thread408-64692 of this Forum.
Hope this helps, 'NGL
