Extended Stem Pneumatic Ball Valve for Cryogenic Service

Cryogenic Extended Stem Pneumatic Flanged Ball Valve with Positioner is a professional low-temperature industrial valve designed for fluid shut-off and regulation under ultra-low temperature working conditions. This Ball Valve can be assembled with Control Valve, Gate Valve, Globe Valve, Check Valve and strainer to construct a reliable fluid control system for cryogenic industrial pipelines.   Adopting an extended stem structure, the valve effectively isolates low temperature from the top actuator and protects sealing assemblies from frost damage. The flanged connection ensures stable and tight pipeline connection with excellent pressure bearing performance. Equipped with a pneumatic actuator and positioner, the valve achieves accurate remote flow adjustment and automatic cut-off. Low-temperature resistant materials are adopted for all wetted components to adapt to liquefied gas and other cryogenic media. Every finished valve undergoes precise machining and strict cryogenic sealing tes…
