ASTM B148 C95800 Butterfly Valve is made from high-strength aluminum bronze alloy, specifically C95800. This alloy, known for its strength, is part of a range of aluminum bronze alloys produced by manufacturers like Concast, including C95400, C95500, AMS 4880-C95510, and C95900. Aluminum, along with iron and nickel, acts as a strengthener in these alloys, and they can be further strengthened through heat treatment. Butterfly valves, as a type of quarter-turn rotational motion valve, are widely used in pipelines to regulate or stop fluid flow. They offer advantages such as simple construction, compact design, lighter weight, lower cost, smaller footprint, and faster actuation speeds.
