The butterfly valve has 90. Features such as rapid opening and closing of rotation, light weight, small structure size (especially wafer butterfly valve) and other advantages. However, its sealing reliability is relatively poor, so it is often used in medium and low pressure and medium and low temperature conditions in industrial production equipment. With the large-scale petrochemical production equipment, it is a

Cryogenic valves, as the name implies, are valves that can work in cryogenic and cryogenic conditions. The operating temperature is demarcated. Valves with operating temperatures below -40°C are usually called cryogenic valves, which are mainly used for gas liquefaction, For separation, transportation and storage equipment, the operating temperature can reach below -270℃. Currently, there are gate valves, globe v
