Extended Bonnet Design for Cryogenic Service
Equipped with an extended bonnet structure to maintain the packing area away from extremely low-temperature media, preventing frost formation and ensuring reliable stem sealing performance.
Special Low-Temperature Material Selection
Manufactured with cryogenic-grade materials such as CF8M, CF3M, stainless steel, and low-temperature alloys to maintain excellent toughness and mechanical properties under temperatures down to -196°C.
Reliable Backflow Prevention at Extreme Temperatures
Designed with optimized disc movement and sealing structure to provide fast response and prevent reverse flow in LNG, liquid gas, and other cryogenic systems.
Low Thermal Conductivity Design
The extended neck and optimized valve geometry reduce heat transfer between the cold medium and external environment, minimizing cold loss and improving system efficiency.
