Tank bottom butterfly valve in stainless steel is designed to meet sanitary processing system requirements, acting as ON/OFF valve and available in manual or pneumatic operated versions. Composed of one head, a welding plate and a shutter disk enclosed in a seal gasket. Thanks to their internal design and the wide bore, they guarantee a gentle treatment of the product flow, a minimization of turbulence, contamination and a low pressure drop. The seal gasket is conceived to be flush to the internal passage, avoiding product entrapment.
