Any fire-safe version for triple offset?

[SmithsJohn2]

Is there any fire-safety version of triple offset? This is all metal butterfly valve, without any plastic material? Should be inherent fire-safe? Thanks for comments.

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
