SISTO Armaturen S.A

SISTO Armaturen AG is a specialist manufacturer of diaphragm valves for sterile applications and is part of the international KSB group.

SISTO's solutions are developed to meet the highest levels of product purity requirements, both in the manufacture of pharmaceutical substances and in the food and cosmetics industry. SISTO-C's unique sealing system , featuring a recessed membrane and helical backing, ensures maximum life and pressure range. A flow without dead zones gives optimal conditions for the preservation of the purity of the fluid. Constant improvement of our membranes also allows us to increase their operating safety and reduce downtime.

The manufacture of aseptic diaphragm valves, their pneumatic and manual controls and all their essential components is done exclusively in our establishment. Thus, all the decisive steps contributing to the quality of the product, such as the vulcanization of our membranes, the mechanical polishing and the electropolishing, are carried out in-house. Our high degree of integration allows us a complete monitoring of the quality but also a great flexibility of manufacture to realize also individual solutions in small volumes or to answer particular needs of our customers.
