How to calibrate pneumatic metal hard seal three eccentric butterfly valve?

1. The water line planning of the seal valve seat and the plane planning of the valve plate sealing surface completely prevent the electric valve from being stuck due to long-term non opening
2. At the upper and lower middle holes of the valve plate, spherical conflict surface is selected for planning, with less torque and better sealing
3. The valve seat has no backrest, and the torque is lighter. It is also convenient for users to replace the valve seat by themselves
4. Various specifications apply to the connection of flange to clamp hole

Pneumatic butterfly valves are very suitable for making switches and cutting off valves. With the development of science and technology, people have redesigned the valves to have flow control and control functions. For example, the V-shaped spherical valves, which are common in our lives, can control the transmission of water, volume, natural gas and other media. At the same time, they can also be used in environments with poor conditions, and have strong adaptability.
