APPLICATION

SV-1MPBPW (B type) series is a pneumatic operated Sanitary Mixproof Butterfly Valve with double seat design. As a process element for the sepatation of media, it is widely used in variety of applicaitons. AV-1MPBPW butterfly valve operates automatically.

The B type double seat butterfly valve has two discs, it can be used in food-processing, pharmaceutical and chemical industries. Leakage butterfly valve offers an easy and safe separation of products and prevent accidental mixing in case of gasket failure. The most used applications are the ones that require safe separation of the product and CIP solutions in a single point (not in manifolds), or at the end of a manifold (e.g. CIP return) or entry of a CIP solution in a tank (through a sprayball).

Pneumatic actuator with IL-TOP available for intelligent control, contact factory for more details.
