Application and design requirements of medium and high temperature pneumatic ball valves in foreign power plants Pneumatic ball valves were only used for normal temperature and low temperature pipelines in the past, and their maximum operating temperature generally did not exceed 150 degrees. At present, some products abroad have been applied to power plant pipelines with medium temperature (above 260 ℃) and high pressure above 0.5MPa. In the near future, it is possible to replace expensive gate valves and globe valves.
