Food processing valves

The food industry is subject to numerous requirements, standards and controls.  Reconciling product quality and compliance with standards and regulations is a challenge for many companies.

Sealing solutions in the food industry must therefore fulfil their sealing function and at the same time be resistant to cleaning chemicals, temperature and steam. When producing seals for the food industry, many ingredients are completely banned and migration limits are constantly decreasing. Therefore, it is more and more complex to find suitable material compounds that comply with the standards applicable to each economic area.

For more than 40 years, Techné has gained a strong expertise in the design and production of seals specifically developed for the food industry.
