The valve body has flanges at both ends, corresponding to the flanges on the pipeline, and is installed in the pipeline by bolting the flanges. Flange connection is the most used connection form in valves. Flanges are divided into raised surface (RF), flat surface (FF), convex and concave surface (MF) and so on. According to the shape of the joint surface, it can be divided into the following types:

Leakage of the valve: First, when the valve and the pipeline are flanged, the leakage occurs due to the asynchronous shrinkage of the connecting gasket, the connecting bolt, and the looseness between the materials of the connecting piece at low temperature.

The valve body is available in a wide variety of materials and is suitable for a variety of different working conditions. Common materials for valve bodies are as follows:
