Which parts of the butterfly Valve consist of? In this article, the editor of Bundor Valve will take you to understand.
The components of the butterfly Valve include: Valve body, butterfly plate, Valve shaft, Valve seat, and drive these five main parts. Each part has a different material, and the combination is suitable for different working conditions.
Valve body: There are two common connection methods: wafer and flange. Common materials include gray iron, ductile iron, cast steel, and stainless steel. Stainless steel butterfly Valves have the highest cost and are mostly used in industrial pipelines, which can resist corrosion and rust, and are resistant to high temperature and high pressure; gray iron and ductile iron butterfly Valves are mostly used in wading pipelines, low pressure and normal temperature environments; cast steel butterfly Valves are mostly used in ordinary industrial pipelines Above, although the corrosion resistance is not as good as the stainless steel butterfly Valve, it can also withstand high temperature and pressure.
Butterfly plate: The material of the butterfly plate of the center line butterfly Valve and the eccentric butterfly Valve is also different. The disc materials of the centerline butterfly Valve are DI, CF8, CF8M, C954; the disc materials of the eccentric butterfly Valve are WCB, CF3, CF3M, CF8, CF8M.
Valve shaft: soft sealing butterfly Valve shaft material usually uses 45# steel, 420 stainless steel, 304 stainless steel, 316 stainless steel; hard sealing butterfly Valve shaft material mostly uses 2Cr13 series stainless steel, 304 stainless steel, 316 stainless steel.
Seat: The seat of the soft-sealed butterfly Valve is mainly made of EPDM, NBR, PTFE, and PTFE; the seat of the hard-sealed butterfly Valve is made of stainless steel, 304 stainless steel, and 316 stainless steel.
Drive: The commonly used drive devices for butterfly Valves are: handles, worm gears, el ectric actuators, and pneumatic actuators. Common handles include stamped handles, large iron handles, and aluminum handles; worm gear heads are made of cast iron and stainless steel. Worm gear heads are also divided into single-stage worm gear heads and double-stage turbine heads. The main difference is the size of the butterfly Valve diameter; electric actuators have On-off type and regulating type; pneumatic actuators are divided into single-acting and double-acting.
The above is the introduction of the butterfly Valve components of Bundor Valve. Understanding the composition of the butterfly Valve is of great help to the selection of the butterfly Valve.
