Introduction
A cryogenic ball valve is a type of valve specifically designed for controlling fluid flow in extremely low-temperature systems. It is widely used for its superior sealing performance, minimal flow resistance, and fast 90° operation. Typically featuring a top-entry design, it allows for easy online maintenance. The extended stem ensures that the bearings and packing box remain at ambient temperature, preventing freezing and guaranteeing smooth, reliable operation.
Specially designed flexible graphite packing and lip-shaped seals effectively compensate for thermal expansion and contraction caused by temperature fluctuations.
Key Features:
① Low operating torque for effortless operation
② Quick 90° opening and closing
③ Extremely low flow resistance
④ Reliable bi-directional sealing
⑤ Easy maintenance for online service
Applications:
① LNG plants, storage tanks, and filling stations
② Air separation units
③ Various cryogenic process systems
④ Ideal for applications requiring high sealing performance and frequent operation
