Low Temperature Ball Valve

The low temperature ball valve is resistant to frost cracking, high temperature deformation, corrosion and dirt, ensuring the safe operation of pipelines. It is one of the important equipment for transporting low-temperature liquids, mainly used for the output of liquid low temperature media such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc., not only flammable and explosive, but also gasification when heating, gasification, the volume expansion of hundreds of times.

Design Advantages

The structure adopts a pressure reducing hole on the valve core.

The gasket is made of ceramic filling material with stable sealing properties.

The ball valve channel is flat and smooth, and it is not easy to deposit media, allowing for pipeline ball connection.

Long valve stem form, maintaining normal temperature and sealing of the gland.

A drip plate structure can be installed to avoid or reduce the transfer of low-temperature medium temperature to the valve stem and the filling material on its upper end.

Anti icing and anti freezing measures to prevent valves from freezing under low temperature conditions.
