Sanitary Flanged Butterfly Valve
The Sanitary Flanged Butterfly Valve connects to piping systems via flanged end faces, making it suitable for larger diameter pipelines and higher-pressure applications. The flanged design provides easy bolt-on installation and removal without cutting the pipeline. It complies with international flange standards (DIN, ANSI) and maintains full hygienic performance across all wetted surfaces.
