Structural Characteristics of Cryogenic Ball Valves
- Extended Valve Cover Design
– The valve has an extended cover design to ensure thermal isolation between the valve body and the operating mechanism. This design reduces the impact of low temperatures on valve operation and ensures flexibility.
- Two-Way Sealing Structure
– The valve features a two-way sealing structure to ensure zero leakage in any flow direction. This is crucial for systems requiring bi-directional flow.
- Anti-Static Design
– The valve is equipped with an anti-static device. The ball and valve body are electrically connected through a metal grounding device. This prevents static sparks and ensures safe operation in flammable media.
- Fire Safety Design
– The valve has a fire-proof structural design. It provides additional safety in case of fire. This prevents valve failure from causing media leakage.
