excellent regulated performance.

diszdvantage

The range of working pressure and woking temperature are small

Poor sealing

Butterfly valve according to the structure of the form of bias can be divided into theplate, vertical plate, inclined plate and leveraged. It is also devided into soft and hard sealing.
