Detail Information

Electric soft seal butterfly valve whose applicable temperature belows 150℃ consists of PTFE seat, stainless steel valve disc and valve stem. The valve can only be used under weak corrosive condition or merit rating. Triple offset hard seal valve body can be used under high temperature and pressure. So it needs to be noted when ordering. In food, chemical industry, petroleum and other industries, electric soft seal butterfly valve can be used to realize automation and it can also regulate flow and closure medium.

Characteristics of electric soft seal butterfly valve

1. Novel design, unique structure, light weight, rapid open and close

2. Small torque, convenient operation

3. Can be install in any position and it is convenient maintain.

4. Seal can be replaced and realize bidirectional sealing and zero leakage.

5. Aging resistance, corrosion resistance and long service life.
