Ball valve body casting structural characteristics and material selection
- Nov 14, 2018 -

Ball valve body castings may be of unitary construction or may be combined. The so-called ball valve casting is the valve that the opening and closing member ball is driven by the valve stem and rotates around the axis of the valve stem. Ball valve body castings are mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control.


Ball valve body castings are widely used in various industries. They are characterized by compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and the spherical surface are often closed, which is not easily eroded by the medium, and is easy to operate and maintain. These castings are suitable for general working media such as water, solvents, acids and natural gas, but also for media with harsh working conditions such as oxygen, hydrogen peroxide, methane and ethylene.


When applied in pipelines, ball valve body castings are usually installed horizontally, including pneumatic ball valves, electric ball valves, manual ball valves, high pressure ball valves, welded ball valves, and forged steel ball valves. Wear-resistant ball valve body casting materials are usually carbon steel, duplex steel, acid wet H2S medium carbon steel.
