Sealing for API 6D ball valve and LNG at cryogenic temperatures has its own unique set of challenges. JST has a wide range of solutions for cryogenic sealing applications. The range includes valve stem seals and valve seat seals. Compounds and designs could vary as per specific applications.

The material mainly includes polymer jacket (virgin PTFE, filled PTFE, TFM, PCTFE, UHMW-PE, PEEK, etc.) and SS /Elgiloy/lnconel helical spring, canted level spring, canted coil spring.

Material compounds have passed API 6A FF/HH Immersion Testing and NACE approved energizers available for oil and gas application.
