Mixproof valves

MADE for producers of soup, yoghurt and other liquids with large particles, the new range of mixproof valves from Alfa Laval prevents cross-contamination when handling two liquids, thereby enhancing safety levels.

Alfa Laval is a leading global provider of specialized products and engineering solutions based on its key technologies of heat transfer, separation and fluid handling. Its valves are available for food and non-food products.

The Alfa Laval Unique Mixproof Valves provide maximum flexibility in hygienic flow processing by making it possible to handle two different fluids at the same time, with no risk of cross-contamination. Using two independent plugs and seals means a single mixproof valve can often replace two or more valves of other types.

The company also supplies several different designs of mixproof valves, all with leakage detection, that help boost reliability and safety levels. They enable users to design versatile set-ups that are both cost-effective and easy to maintain, and also present them with new processing opportunities.

Tailored to requirements

The Alfa Laval Unique Mixproof Valve is a modular solution that is easily tailored to specific customer requirements. According to the company, customers only pay for the exact features and capabilities needed.

In a nutshell, the valve can offer:

• Low cost of ownership and no risk of cross-contamination
