The electric ball valve operates via a 90-degree rotation; its closure element is a sphere featuring a circular bore or passage along its axis. Primarily used in pipelines to shut off, distribute, or redirect the flow of media, the valve achieves a tight seal with just a 90-degree turn and minimal operating torque. While traditionally best suited for on/off and shut-off applications, ball valves have evolved to include designs capable of throttling and flow control, such as V-port ball valves.
Key characteristics of the electric ball valve include a compact design, reliable sealing, simple construction, and ease of maintenance. Because the sealing surfaces and the spherical closure element remain in contact during the closed position, they are resistant to erosion by the medium. Easy to operate and service, these valves are suitable for general media-such as water, solvents, acids, and natural gas-as well as demanding media like oxygen, hydrogen peroxide, methane, and ethylene, finding widespread application across various industries. The valve body may be of a single-piece or multi-piece (split-body) construction.
