Double-seat valves
FLOWVENT Mixproof valves
State-of-the-art for your secure applications: GEA FLOWVENT Mixproof valves are used for the hygienically safe shut-off of incompatible media at pipe intersections.
State-of-the-art for your secure applications:
GEA FLOWVENT Mixproof valves are used for the hygienically safe shut-off of incompatible media at pipe intersections.
Function
In the closed state of the valve (non-actuated position) there are always two seals between the separate pipelines. If one seal should become defective, the resulting leakage can flow off from the leakage outlet to the periphery in a targeted manner without mixing with the product in the second pipeline. In this way it is ensured that no mixing occurs between the media in two pipelines.
Application
Hygienic applications in dairy before heat-treatment or e.g. in fermentation and storage tank farms and in the brewing and beverage industries.
