Three-Piece Butterfly Valve
The Sanitary Three-Piece Butterfly Valve features a split body design consisting of two end pieces and a central body, connected by clamps. This configuration allows the valve to be disassembled rapidly for cleaning, inspection, or seat/seal replacement without removing the valve from the pipeline. It provides exceptional maintenance accessibility and is favored in processes where frequent valve servicing is required.
