3 Part of Crane Co, a globalmanufacturing and Sales Organisation, CraneProcess Flow Technologies Ltd has a strongworldwide presence via dedicated Salescompanies and distribution K Saunders invented the original diaphragmvalve in 1928. Since then, we have developedour range through innovative designs and byusing the latest materials technology. As aresult, Saunders Diaphragm Valves have gained an excellent reputation for versatilityand reliability establishing a presence in every process industry sector. Today there are millions of Saunders Diaphragm valvesinstalled on process plants around the is one reason above all others for thissuccess: ours are the Valves that engineersknow they can trust.

4 We have set the industrystandard for dependable, consistent operationyear after year under even the most adverseconditions. In choosing Saunders, customersknow they are assured of many years oftrouble-free and reliable products. Customers also know they can depend on us for after sales service, support and technical advice from one of our many locally based Crane sales companies and distribution Original and the BestSaunders Diaphragm valve features and benefitsfor corrosive and abrasive applications with100% leaktight closure operationCompressor supports thediaphragm in all positionsfor longer lifeWide range ofbody materialsavailablePaint finish resists environmental attackWide choice ofdiaphragm materialsprovide positive shut-offand isolate all bonnetworking parts from theline fluidBody end connections screwed.

9 A wide choice is available for materials, methods of operation and body end connections to satisfy the needs of most corrosive and abrasive design for contamination free performance and smooth flow characteristics. Linear operation ensuresvalve does not induce damaging pressure surges or static charges. Three part design allows maintenance and actuator retrofittingwithout removing thevalve from the this results inlower cost of ownershipcompared to other valve 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 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 .

10 Throttling and control characteristics are enhanced by a streamlined flow path that is cavity free and provides excellent flow control life, reliability, safety and ease of use, combined with an essentiallysimple design, results in low maintenance for minimum running of maintenanceValve flow07 Bonnet assemblylubricated for long no additionalgrease.
