Low temperature features and application range
-
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...
