Valworx 574707 air actuated all-stainless sanitary butterfly valves are typically used for food, beverage, pharmaceutical, personal care and pet care applications where sanitary construction is required, as well as for utility, process and corrosive environment applications where quick clamp applications are needed. Spring return actuators use an air pressure signal (80-120 PSI) to open and springs to close the valve.
