Products Details
Overview of electric low-temperature butterfly valve:
Electric low-temperature butterfly valves are mainly suitable for low-temperature working conditions in liquid nitrogen (cryogenic) media such as -40 ℃ to -196 ℃. In order to ensure safe and reliable operation of low-temperature butterfly valves, valve parts have undergone cryogenic treatment before precision machining. The valve cover adopts a long neck structure, which aims to protect the function of the packing box, keep the packing box far away from low temperature, and ensure the sealing effect of the packing. Electric low-temperature butterfly valves typically use low-temperature fluids such as liquid helium, liquid hydrogen, liquefied natural gas, liquid nitrogen, and liquid oxygen.
Characteristics of electric low-temperature butterfly valve:
The material of the pressure bearing parts of the electric low-temperature butterfly valve can withstand the expansion and contraction caused by changes in medium temperature, and the structure of the sealing part will not undergo permanent deformation during temperature changes. The extended upper valve cover adopts a double seal with a joint valve shaft, ensuring the long-term stability of the sealing packing at low temperatures. Therefore, it is widely used in the control of cryogenic fluid processes in industries such as liquefied natural gas and air separation.
