Since 1988, SISTO Armaturen S.A. has been an associated company of the KSB Group with KSB as shareholder with 52.9%, and with 47.1% owned by the Luxembourg investment company, SNCI (Société nationale de credit et d'investissement). The company employs around 160 people to research, develop and manufacture valves and related accessories.
The company has more than 40 years of experience in the development of diaphragm valves and actuator technology and is continuously developing new and proven products.
The company uses only the highest quality materials so their valves fulfil the most demanding quality requirements.
SISTO's factory in the city of Echternach in Luxembourg specialises in the manufacture of diaphragm valves, swing check valves and actuators. Since 1994, SISTO has also produced diaphragm valves for sterile processes under the product name SISTO-C. SISTO also develops its own elastomer diaphragms in Echternach.
SISTO valves close softly and can be used safely with pressures up to 20 bar. They are known for their unique sealing system with a closed and spiral supported diaphragm, which in turn increases reliability and diaphragm lifetime. SISTO diaphragm valves are designed to minimise dead volume and provide optimal cleaning conditions.
SISTO diaphragm valves are used worldwide in a wide range of applications, from building services and industry to biotechnology and pharmaceutical sectors.
Within their aseptic SISTO-C series, SISTO produces simple straight (2-way) valves, T-valves and Y-valves (3-way valves) as well as complex multi-seat valves in both very small and very large nominal sizes (up to a nominal size of 200 mm).
As all production processes that affect quality are carried out in-house, SISTO is able to offer highly customised products and the company remains highly adaptable when it comes to meeting changing industry and customer requirements.
The values of trust, honesty, responsibility, professionalism and appreciation are at the core of SISTO and KSB's culture and daily activities. This approach, as well as the company's specific expertise, enables SISTO to offer innovative, high-quality, customised solutions that are at the forefront of process engineering.
