We are looking to purchase some valves which need to be fire safe. We are running into the difference between the safe designed valves and the tested. We are aware of the test criteria for API 607 and what it will mean to be tested. But, what is the criterion to call yourself a fire safe designed valve. Is there a small amount of time that the valve needs to not leak in a fire, like 2 minutes? Is it just having a stem packing rated to a certain temperature, I have seen the most common being 1000f even though the fire test will see 1800F. Any thoughts or factual difference?
