Sanitary Vacuum Butterfly Valve
The Sanitary Vacuum Butterfly Valve is engineered for applications requiring operation under vacuum conditions in hygienic pipelines. The valve body and seat are designed to maintain a reliable gas-tight seal at sub-atmospheric pressures, preventing air ingress and maintaining process integrity. It is commonly used in vacuum transfer, evaporation, concentration, and freeze-drying processes in the food and pharmaceutical industries.
