Information

In order to cope with the regulations on VOC (volatile organic compound) emissions of global chemical process control equipment, API has enacted emission standards on valve fugitive for linear motion valves and 1/4 rotary valves, which are API 624 and API 641 (not officially released). Meanwhile, to control the fugitive of linear motion valves, API has enforced API 624 fugitive requirements on the valves certified by API STD 600 label, meaning that all certified valves must pass the API 624 test. We have built a test bench according to API 624 standards, which can test as large as 20-inch valves. The API 624 can be completed under the witness of a third party.
