Hayward® Diaphragm Valves

Diaphragm valves are engineered to provide superior handling of difficult media such as corrosive fluids, abrasives, and slurries. They can also be used for high purity and sanitary applications. The valve controls flow by varying the space between a stationary weir and a moveable flexible diaphragm. By compressing the diaphragm against the weir, all flow is shut off. Other diaphragms and materials are available; contact us for a quote.
