Flange Type Butterfly Valve

Product Description

The butterfly valve is suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipeline is relatively large, it should also be considered that the butterfly plate is subjected to the firmness of the pressure of the pipeline medium when it is closed. In addition, the limits of the operating temperature of the elastomeric seat material at elevated temperatures must also be considered. The butterfly valve has a small structural length and overall height, a fast opening and closing speed, and good fluid control characteristics. The structural principle of the butterfly valve is most suitable for making a large diameter valve. When a butterfly valve is required for control flow, the most important thing is to properly select the size and type of butterfly valve so that it can work properly and efficiently.
