Claims

[Scope of utility model registration request]

A disc-shaped valve body is rotatably supported by a valve stem located horizontally within the butterfly valve body, which is equipped with a seat ring, which is an elastic sealing material, on the inner circumferential surface. A spherical valve body rotation space having the same center as the main body and an inner diameter matching the butterfly valve diameter is formed between the inlet side attachment and the outlet side attachment to be connected, and a pipe-shaped valve body is formed in the lower half of the space. 1. A butterfly valve for fluid containing particulate matter, characterized in that a flow path is provided through the flow path, and the axis of a valve stem is disposed above the flow path.
