Commonly used in waste and water treatment facilities and systems, butterfly valves use a simple quarter-turn alignment to regulate liquid flow. Similar to ball valves, the precision of the butterfly valve makes them an advantageous choice in industrial and agricultural applications. Butterfly valves are also useful in maintaining pressure levels and regulating precipitous pressure drops. Different types of butterfly valves include stainless steel valves, wafer valves and lug butterfly valves. For more valve options, shop our selection of check and foot valves.
