Pushing the Limits: High-Performance Butterfly Valves Reconsidered

Quarter-turn butterfly and ball valves were introduced in the 1950s to overcome the problems inherent in multiturn linear valve designs, particularly gate valves. The first high-performance butterfly valves entered the marketplace in the ‘60s.

Since then, high-performance butterfly valves have undergone continuous improvement, making them applicable to an increasingly wider range of temperatures, pressures and aggressive media. Within the past few years, the introduction of advanced polymeric seating materials has significantly broadened this range. If you ruled out butterfly valves for some of your unforgiving applications three to five years ago, they now deserve reconsideration.
