By integrating two butterfly discs and independent vent/drain valves into a common housing, the Pentair Südmo Leakage Butterfly Valve completely isolates the self-draining leakage chamber with a single valve housing and actuator. 

The mixproof feature of the leakage detection butterfly valve provides excellent process safety in applications where the separation of incompatible media, e.g. product and cleaning-in-place must be ensured. The special seal geometry with an expansion groove ensures low wear and long service life.
