Soft seal features
1. Structurally: For soft-sealing butterfly valves, the two sealing surfaces in contact can be either alone or all made of soft materials. For example, in a fluorine-lined butterfly valve, the butterfly plate and valve seat are both wrapped in PTFE;
2. In terms of sealing performance: The advantage of the soft-sealed fluorine-lined butterfly valve is good sealing performance, but the disadvantage is that it is prone to aging, wear and short service life.
3. From the conditions of use: The soft-sealing fluorine-lined butterfly valve is used in normal temperature and pressure environments. The fluorine-lined butterfly valve has super corrosion resistance!
4. From the manufacturing perspective: Soft sealing fluorine lined butterfly valve is a non-metallic structure
Butterfly valve flange types
Butterfly valve flange is called flange plate or flanged parts. It is a product that connects valves and pipes in pipelines. Butterfly valve special flanges are the same as ordinary flanges, but the inner holes are different. The special flange for butterfly valve has a small inner hole and an extra slot for pipe insertion.
Butterfly valve flanges can be individual or combined, such as flanges at both ends of the valve to facilitate the installation of bolts. The flange-to-flange connection between one end of the pipe and the other end, or the connection joint, refers to a foldable connection in which flanges, gaskets and bolts are connected to each other as a set of combined sealing structures. Pipe flanges refer to pipeline devices. The flange used for central piping refers to the flange of the valve. The flange has holes. Bolts tightly connect the two flanges, and the flanges are sealed with gaskets.
