Double Flange Butterfly Valves are rugged, versatile and dependable valves routinely used in water filtration plants, pumping stations, pipelines and power plants to isolate equipment or systems. 

The valve utilizes a high strength ductile iron body containing a molded and vulcanized Buna-N or EPDM rubber seat in combination with a 316SS disc seat for bi-directional tight shutoff at low and high pressure.
