Metal sealing is not affected by low temperature. Underlow temperature or room temperature, the valves have the same performance and operating torque.
The valves use extended bonnets to keep the packing away from low temperature area.
Low temperature testing standard : BS 6364

MSS SP-134; dissipation discharge testing standard :

API 622, API 624, ISO/CD 15848, EPA Method 21

Widely used in low temperature media, such as LNG, liquid nitrogen, liquid oxygen ect...
