Product Description
A Butterfly Valve Welded Type body can be made of cast iron, ductile iron, aluminum, carbon steel, stainless steel, and exotic metals. The butterfly valve is classified as a quarter-turn valve. It works like a ball valve for quick shutoff, but unlike a ball valve, the butterfly valve can also open and close incrementally. This difference means that the Butterfly Valve Welded Type is always present in the flow and allows for a pressure drop.
