Vanne papillon à souder bout à bout
The Sanitary Welded Butterfly Valve is engineered for permanent pipeline installations where leak-free, long-service joints are essential. Both ends are butt-welded directly into the pipeline, eliminating the need for gaskets or clamp connections and providing maximum structural integrity. The internal wetted surface is polished to hygienic standards to ensure product purity.
