Saunders Diaphragm Valves
Saunders DiaphragmsSaunders Diaphragm are manufacted in house for use in the saunders range of valves and are available in a range of rubber and rubber backed PTFE dependant on application. General key considerations are: High flex performance, Good compression set properties, Chemical resistance, Abrasion resistance, Anti-aging, Approvals and traceabilty.
Valve LiningsSaunders A and KB type valves come unlined as standard. However they offer a range of solutions to suit corrosive and abrasive media. Ensuring realiable leak free valve operation and maintenance.
A Type (Weir) ValveSaunders A type diaphragm valves have been developed to handle a wider range of fluids and gases than any other valve type. A wide choice is available for materials, methods of operation and body end connections to satisfy the needs of most corrosive and abrasive applications. On pressure and vacuum, Saunders diaphragm valves operate and close 100% leaktight even after thousands of operations. This feature reduces processing and handling costs, by eliminating emissions normally associated with conventional valve designs. All working parts of the valves are isolated from the line media and positive closure is obtained even on frequent cycling or with entrained particulates in the line unlike quarter turn ball and butterfly valves. Throttling and control characteristics are enhanced by a streamlined flow path that is cavity free and provides excellent flow control capabilities. Extended life, reliability, safety and ease of use, combined with an essentially simple design, results in low maintenance for minimum running costs.
KB type (Full bore) ValveSaunders full bore KB type diaphragm valves with their smooth non-turbulent body design have proved to be outstanding in resisting the erosive effects of corrosive and corrosive/abrasive line media. In addition, the full bore concept is designed for minimum flow resistance whilst allowing rodding out and easy cleaning. Low pressure drop and high flow characterise the efficiency of operation of these valves. The flexible diaphragm ensures consistent leak tightness even when solids, powders and dry media are present. Valve blockage and wear due to slurry build up on the valve internals are significantly reduced by the straight through design. In addition to the range of unlined screwed and flanged bodies, rubber linings and glass coatings are available for the more exacting corrosive and abrasive applications to a maximum working pressure of 10 bar.
