Tuchenhagen invented the mix-proof valve in 1966 (VARIVENT System).
The VARIVENT® system is more than just a valve - it is a low maintenance, and modular design system that favors all applications, ensuring both product and hygiene integrity. But through ongoing R&D we continuously expand and improve our range of products:
- Type N & U
- VARIVENT® Double Seal Valves
- VARIVENT® Shuttle Valves
- VARIVENT® Butterfly Valves
- VARIVENT® Longstroke Valves
- VARIVENT® Mixproof Valves
