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.

The T-Coat® surface coatings provide a solution to many of the problems customers face with regard to slippage during the mounting and use of food seals. 

Two of the surface coatings proposed by Techné are approved for the food industry:

  • T-Coat® PPA surface coating is FDA and CE 1935/2004 approved, improves the sliding capacity and mounting of the food seals.
  • T-Coat PA® surface coating has 5 approvals for the European, Asian and American market (FDA, CE 1935/2004, UBA, W270, NSF H1 and WRAS) and improves likewise the sliding capacity and the mounting of the food seals.
