Well-designed products
Our stainless steel valves are used in plants where maximum sterility is required – for example in the pharmaceutical or food industry.
SISTO diaphragm valves are characterised by a unique sealing system that ensures operational reliability and maximises the service life of diaphragms.
In addition, our modular system allows individual solutions even with short planning lead times.

READ MORESterile technology for the highest requirements
Sterile process engineering is an area which places the highest demands on the materials, the design and the manufacture of the components.
The application areas of sterile processes are diverse, with a focus on the pharmaceutical and biotechnology industry, where valves are used under sterile and aseptic conditions for the production of active medical ingredients and products such as vaccines, insulin, vitamins or enzymes.
SISTO has been able to set new standards in these applications through a high level of vertical integration, customised solutions and the development of a unique chambered sealing system.
