Let's briefly talk about the most commonly used electric rubber butterfly valve and electric hard seal butterfly valve.
1、 Electric soft seal butterfly valve (the raw material of butterfly valve here is ductile iron, rubber seal) This electric butterfly valve is often used for opening and closing of non corrosive water at normal temperature. There are two reasons for its leakage:
1. The butterfly plate is corroded. As it is a ductile iron plate, the valve plate will rust and leak after a long time.
2. The rubber valve seat is damaged, and the rubber wear resistance is poor after a long time of opening and closing, resulting in seal damage.
3. Due to the electric actuator, the field commissioning was not in place, resulting in leakage.

In the process of understanding the electric three-way ball valve, people can understand that it is a kind of rotary shut-off valve device. As long as it can be correctly installed in the pipeline, it can achieve more ideal work results in the production process. All friends should master this part of specific knowledge with a more serious attitude. From the perspective of actual production control of various substances, people can also realize that the scope of specific applications is very wide.
