The 20W3080 Bronze Disc Actuated
Butterfly Valves are commonly used for seawater applications where they external body of the Valve is not directly exposed to the elements of corrosive environment. Each Valve features a "Dry Shaft" design feature ensuring that the medium never comes into contact with any other materials other than the Disc & Seat. Thus ensuring extended life of the Actuated Butterfly Valves and vastly reducing the cost to that of a full Aluminium Bronze Bodied Butterfly Valve.
