Saunders® Industrial Diaphragm Valves

The Saunders® Industrial Diaphragm Valve, first developed more than seventy years ago, has evolved to handle more fluids, gases, solids, and powder than any other type of valve.

A wide choice of materials are available and a flexible range of operating methods have been developed to satisfy the needs of most industrial applications.


Extended life, reliability, safety and ease of use, combined with an essentially simple design, facilitate low maintenance and minimal running costs. When subjected to both pressure and vacuum, Saunders® diaphragm valves operate and close 100% leak tight. This feature reduces processing and handling costs by cutting out the waste normally associated with conventional valve designs.
