Fire Test API 607
Fire Test API 607
(OP)
Dear all,
Its not very long ago that I am into valve engineering and I am finding problems to understand some matters of fire test in valves. How can it be that we are asking for an API 609 soft seated valve that acomplish requirements of API 607, as far as I know PTFE should not be used with temperatures above 200ºC, thus how can it stand temperatures between 750 and 1000ºC without burning the seat?
Thanks in advance!

Soft-seated valves normally have back-up metal-to-metal contact surfaces inside or back-up graphite seals to provide some measure of shut-off after the plastic parts are burned.
