Butterfly Valves set the standard for the handing of powders, granules, pastes, liquids, and gases in the hygiene conscious industries. They are able to seal against pressure or vacuum and offer superior quality coupled with the latest design and technology available for a single vane valve.

The butterfly valve has a wafer style design to keep a seal against differential pressures above and below in order to prevent any backflow and allow for single direction flow. It achieves this by using a tightly fit seal (available in a variety of materials) against the sides of the flat valve vane.
