Critical Design and Production Tips on Cryogenic Ball Valve (Stem Packing)

Cryogenic Valve stem icing during the application was alway the critical and difficult problem for the valve manufacture. C Tech Science and Technology Co., Ltd redesigned and improved the traditional stem packing design with special triple sealing Design. This increased the stem packing sealing performance. and the valve are successfully meet the fugitive emission test of Class B as per ISO15848-2. To most of the extent, this design reduced the possibility of valve stem icing during the application.
