SISTO Armaturen S.A is an associated company of the KSB Group, a globally active manufacturer and provider of pumps, valves and service, as well as of SNCI, a Luxembourgian public-law banking institution. SISTO has about 150 employees developing and producing diaphragm valves. The unique technology of the SISTO diaphragm valves has been proven million-fold in operations. In order to fulfill the stringent requirements of customers and always comply with the latest technology, all quality-influencing production processes are carried out on the premises of SISTO: from turning and milling with modern 5- to 9-axis machines to surface machining and electropolishing. Even the vulcanization process for manufacturing diaphragms takes place in our own factory. Not only does this setup allow an end-to-end quality surveillance, it also gives us the flexibility for a high degree of customization and small batch sizes up to single-piece production. Besides our product line „SISTO-C“ for aseptic processes, we are also producing diaphragm valves and swing-check valves for industrial applications (e.g. processing of chemicals), building industry applications or power plants. These products are available with different coatings and linings, e.g. PTFE and soft- or hard rubber. They are complemented with a full range of piston or diaphragm actuators.
