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.
