Butterfly Mixproof Valve

The Butterfly Mixproof Valve, also known as the Leakage or Block & Bleed Butterfly Valve, is an advanced valve that not only delivers exceptional separation and mixing capabilities for 2 applications but also incorporates a leakage chamber for enhanced functionality. Benefiting from the advantages of the standard Butterfly Valve, The Butterfly Mixproof Valve delivers the added feature of mixproof technology. This technology employs a dynamic mechanism that uses 2 discs and 2 seals to effectively separate the 2 applications when the valve is closed. On the other hand, when the valve is open, it facilitates seamless blending of the 2 applications.
