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...
