   Butterfly valves belong to the quarter-turn rotational motion valves family and are used primarily to stop, regulate, or start the flow. The term “butterfly” in a butterfly valve is actually a disk that is connected to a rod. When this rod rotates the disk by 90° the butterfly valve opens or closes.

   What are the different types of butterfly valve?

   • Butterfly valve can be divided into offset plate type, vertical plate type, inclined plate type, and lever type according to the structure form. According to the sealing form, there are two types soft sealing type and hard sealing type. The soft seal type generally adopts a rubber ring seal and the hard seal type usually adopts a metal ring seal.

   How does a butterfly valve work?

   • In this design, the valve stem passes through the centreline of the disc. This is also known as a zero-offset valve. Concentric butterfly valves are used for low-pressure services. In an eccentric butterfly valve, the stem does not pass through the centerline of the disc. There are three types of offset valves.

    Jun 3, 2023 · A Butterfly Valve is a types of valve that isolates and regulates the flow of a fluid by a disc provided across the bore of a ring body having the same radial dimensions as the pipe in which it is fitted. It comes among the family of quarter turn valve and working is same as ball valve.
