The jacketed structure facilitates online maintenance. Without the need to dismantle the pipeline, the valve seat or sealing parts can be quickly replaced, significantly reducing maintenance costs. The fixed ball design reduces valve ball wear, and in combination with the low-torque valve stem bearing system, the operation is lightweight and has a long lifespan. The ultra-low temperature adaptability is verified through material optimization and structural simulation, avoiding cold flow phenomena; the bidirectional metal sealing structure maintains sealing integrity under high pressure differences. The overall design takes into account both lightweight and high strength, supporting electric, pneumatic or manual drive, meeting the requirements of automated control, and suitable for deep cold environments with high safety requirements.

This product is a new type top entry combination ball valve,the seat can be installed and move around the body. Through the thread, the outer margin of the seat connected to the retainer ring. There is spring on the support cover, which installed on the valve body, and the retainer ring can compress spring.
The valve disc of the Cryogenic Lifting Check Valve adopts a vertical lifting structure and is equipped with a cobalt-based alloy sealing surface. It can achieve rapid response and reliable sealing when the medium pressure changes. The product complies with BS 6364 and API 6D standards and is suitable for the transportation systems of low-temperature media such as LNG and liquid oxygen. The working pressure can reach Class 2500 and meets the strict working conditions requirements in the petrochemical and air separation fields.
The Top Entry Cryogenic Floating Ball Valve is a valve suitable for ultra-low temperature environments, mainly used to connect or cut off low-temperature media.
