How big is the DN80 bolt of pneumatic high-temperature regulating butterfly valve with manual and automatic non response? The pneumatic butterfly valve must be actively maintained during use. This is the most fundamental and critical issue for us. Once we have no understanding of this, how can we do a better job in the whole maintenance and fully realize the smooth use in the future?
、 The flow characteristics of pneumatic butterfly valves are mainly shown in the resistance during flow, discharge capacity, flow quantity characteristics, sealing grade, etc. The special properties of materials during operation are mainly shown in the pressure, operating temperature, corrosion characteristics, whether solid particles are included, whether the medium is toxic, whether it will cause combustion and explosion, and the viscosity of the medium.
