The Segmented Ball Valve Series 19/19L is a precision-engineered control valve designed for throttling and shut-off functions in a variety of industrial systems. The valve body is constructed from robust metal, typically stainless steel or carbon steel, with flanged ends to meet standard ANSI or DIN specifications.
This valve features a segmented V-notch ball that provides excellent control characteristics, such as equal percentage flow. The top flange includes an ISO 5211 actuator mounting pad, enabling easy adaptation for pneumatic or electric actuation. Its design allows for reliable performance in high-pressure and high-cycle environments such as chemical plants, pulp and paper mills, and oil & gas pipelines.
