Butterfly valves are widely used in petroleum, chemical, environmental protection and other industries, mainly because of the following characteristics:

  • Simple structure, small size, light weight, easy installation.
  • The opening and closing are quick, labor-saving, and the fluid resistance is small.
  • It can be rotated at any angle and has good adjustment performance.
  • Good sealing performance, no friction between sealing surfaces during opening and closing, less wear and long service life.
  • Easy to operate, remote operation and automatic control, and automatic operation can be set according to the program.
  • To achieve complete sealing, it can also be used in vacuum systems.

U Section Butterfly Valve

VALTECCN butterfly valve manufacturers and suppliers tell buyers to consider the following factors when choosing U section butterfly valves:

  1. Valve body material: Valve bodies of different materials have different performances and characteristics. Common materials include stainless steel, cast iron, cast steel, ductile iron, carbon steel, alloy steel, etc. Choosing the right body material can ensure the long life and stability of the butterfly valve.
  2. Medium temperature: Butterfly valves are suitable for fluid control at various temperatures, including normal temperature, medium temperature and high temperature, etc. Selecting a butterfly valve suitable for the temperature range can ensure its normal use under various working conditions.
  3. Flow coefficient: The flow coefficient refers to the ratio of the flow rate of the medium flowing through the valve body to the throat diameter of the valve body. Choosing an appropriate flow coefficient can ensure the opening and closing speed of the butterfly valve and the accuracy of flow control.
  4. Opening and closing torque: The opening and closing torque refers to the torque required during the opening and closing process of the butterfly valve. Selecting an appropriate opening and closing torque can ensure the stability and rapidity of the opening and closing of the butterfly valve.
  5. Sealing performance: The sealing performance of the butterfly valve refers to the sealing performance between the butterfly plate and the valve body. Choosing a suitable sealing form can ensure that the butterfly valve will not leak during the opening and closing process, thereby ensuring the stable operation of the system.
  6. Use environment: Different use environments have different requirements for butterfly valves, such as high temperature, low temperature, strong acid and strong alkali, etc. Choosing a butterfly valve suitable for the use environment can ensure its normal use in various harsh environments.
