Difference between wafer butterfly valve and grooved butterfly valve

What is the difference between  wafer butterfly valve and  grooved butterfly valve? Bundor Valves introduce to you.

There are many classifications of wafer butterfly valves, and their uses are also very wide. The wafer butterfly valve body is short and simple in structure, and only needs a few parts. The common wafer butterfly valves are cast iron, cast steel, and stainless steel, which are cheaper. Installation is simple and can be directly connected to the two flanges of the pipe with a few bolts.
Wafer butterfly valves are widely used and are used in water system pipelines. Wafer butterfly valves are used in pipelines such as building water supply and drainage, municipal water, water conservancy projects, and even some oil-passing pipelines. Wafer butterfly valves are also used.
Grooved butterfly valves are mainly used in fire pipelines, and wafer butterfly valves are used in ordinary pipelines.
Features of grooved butterfly valve: simple structure, simple operation, can be rotated by handle or turbine; low price, the current valve body is small body, mostly made of ductile iron; simple installation, the connection between the valve and the pipeline requires a clamp Just fine, no need for flanges and bolts.
Grooved butterfly valves are mainly used in fire pipelines. Most of these pipelines have no practical application after completion, so they do not need to be replaced frequently.
