February 06, 2023


We are happy to announce KI has passed the requirements for fugitive emission according to standard: API standard 641, first edition, October 2016 “Type Testing of Quarter-turn Valves for Fugitive Emissions”.

Our valves were tested under TUV supervision by an independent third party and pass the API 641 standard that applies to all stem seal materials and requires a stringent maximum allowable leakage of 100 parts per million by volume (PPMv). With the importance of environmental safety growing nowadays, it is more important than ever to ensure our ball valve products adhere to the most current Fugitive Emissions standards in the industry.
