How is the connection of pneumatic high-temperature butterfly valve different from that of solenoid valve?

Now, as a component used to complete the on-off and flow control of pipeline system, pneumatic butterfly valve has been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower and so on. Among the known skills of pneumatic butterfly valve, the sealing method mostly adopts sealing structure, and the sealing materials are rubber, polytetrafluoroethylene, etc. Due to the constraints of structural characteristics, it is not suitable for industries such as high temperature resistance, high pressure resistance, corrosion resistance and wear resistance.
1. The sealing surface leaks, and the butterfly plate and sealing ring of the butterfly valve contain sundries.
2. The butterfly plate and sealing position of pneumatic butterfly valve are not aligned.
3. The outlet is equipped with flange bolts that are not pressed or stressed.
4. The pressure test direction is not as required.

、

The only way to deal with it is to replace the sealing ring. It is believed that the seal ring is a very important part of the pneumatic butterfly valve, and also an indispensable part.
