Butterfly Valves

In 1951 Keystone Valves launched a new valve concept - the rubber seated butterfly valve. Since then, through constant innovation and customer feedback, Pentair offers trims and sizes of butterfly valves to suit most applications having to do with isolation and control of liquids, gases or slurries. By both mechanical and polymer engineering Keystone butterfly valves have a strong focus on providing valves that offer long life through high cycle capabilities.  Benchmarking ensures Keystone remains a leader in this critical area against other makers of butterfly valves for the process sectors.
