The DQ41 low-temperature ball valve is suitable for the management system of low-temperature liquid storage and transportation equipment. It features flexible opening and closing and reliable sealing. It can also be used in the management system of other low-temperature and cryogenic media. This product is mainly used to output liquid low-temperature media such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, and liquefied petroleum products. The flange low-temperature ball valve is divided into two types: low-temperature floating ball and low-temperature fixed ball. It is used to cut off or connect the low-temperature media in the pipeline. The low temperature must not be lower than -196 degrees.
