What is a floating ball valve?
A floating ball valve is a valve in which the ball can float. Under the action of medium pressure, t...
The Cryogenic Ball Valve is designed to operate in ultra-low temperatures—down to -196°C (-321°F)—for applications such as LNG, liquid oxygen, nitrogen, ethylene, and hydrogen. This valve ensures tight shutoff, anti-leakage, and material stability under cryogenic conditions, making it essential in gas processing, energy transport, and scientific storage systems.
