What is the difference between a clamp butterfly valve and a flange connection?

1, The structure is different: flange connection is the bolt to connect the two end faces together; The clamping type is to squeeze the two sealing rings together by the nut to ensure the tightness of the connection.

2, The installation position is different: the clamping type is installed in the diameter direction of the pipeline (that is, perpendicular to the direction of the channel), and the installation of the flange is in the horizontal direction of the pipeline.

3. Different uses: flanges are mainly used in gas or liquid conveying systems in high temperature, high pressure and low temperature and low pressure environments, as well as industrial production process systems under harsh working conditions such as flammable and explosive; For the clamp butterfly valve used under normal temperature and pressure or low pressure conditions, its role is mainly as a closure device to control the flow direction and speed of the liquid.
