What is API 607 standard?
API 607 is a fire testing standard specifically for valves, established by the American Petroleum Institute (API). Its core focus is to evaluate the sealing integrity and operability of valves under extreme fire conditions. The certification requires that after being exposed to a high-temperature fire of 650°C for 30 minutes, the valve must maintain structural integrity and pass both low-pressure and high-pressure leakage tests, with leakage rates strictly controlled within industry-acceptable limits.

What is the difference between API 6FA and 607?
API 607 and API 6FA are fire tests for valves under standards 6D and 6A. Generally, 6D valves that rotate 90° require API 607, while others need API 6FA. API stands for the American Petroleum Institute, and 6FA is the fire test standard for 6A specification valves.
