In a segmented ball valve for low noise and anti-cavitation applications, a replaceable cartridge is fixed inside and retained by stem and end post. The segment has a machined cylindrical bore with a slide-fit noise cartridge, enabling field replaceability with minor effort & without need of welding or fasteners. The replaceable cartridge also enables use of a fully cylindrical cartridge with greater pressure reduction stages compared to welded-on noise plates on the segment. The segment has a flattened front face resulting in lower Fd enabled by dual flow path in lower openings values thereby attaining higher noise attenuation where the cartridge is not required. The curved plates of the low noise and anti-cavitation cartridge enable: expanding flow resulting in non-impinging jet streams thereby achieving higher noise attenuation in one direction; and converging flow in the opposite direction resulting in reduction of flow energy, and the potential for cavitation for liquids.
