ASTM A995 5A Butterfly Valve is a valve made from austenitic-ferritic (duplex) stainless steel, adhering to the ASTM A995 standard. These valves are designed for use in pipelines to control flow, characterized by their quarter-turn rotational motion. They offer advantages such as simple construction, compactness, lightweight, and faster actuation speeds compared to other valve types. These valves find widespread application in water supply, distribution, and pumping stations, among other industries.
