Fire safe test for 4-way switch coker ball valve ?

(OP)
Dear friends,

This is related to coker unit.
I am prepearing Data sheet for special 4-way ball valve & i want to know whether Fire Safe Testing willl required or not ??  

RE: Fire safe test for 4-way switch coker ball valve ?

I don't think that fire safe testing is required.  These are special valves that operate above 900 degree F - and are used for selecting the drum instead of isolating the drum.

BTW the licensor for the technology likely provides a specification for the available switching valves.
