Manufacturers of food and different hygienically processed merchandise face the problem of maintaining reproducible processes so that their products have the looks, style, and consistency that buyers anticipate.
GEA has designed the VARIVENT MX with components that keep products from mixing with the cleansing liquid, even underneath distinctive loads. The cavity chamber is fitted with a vacuum self-drainage system and balancers on each valve discs. For maximum physical safety, GEA makes use of the Venturi impact which is created by the particular shape of the circulate channels, causing a vacuum on the alternative seal during lifting, preventing pressure will increase. As a end result, no cleansing liquid can enter the opposite pipe carrying the product while a valve seat is being lifted or cleaned, even if a seal is defective.
When new methods are set up and adjusted in a short time, there is a larger danger of overpressure during operation. The valve discs must stay in place when water hammer occurs, and the valve should remain closed. For this purpose, GEA has outfitted the valve discs in both pipelines with balancers – stress compensators. This makes the closed valve resistant to water hammer as much as 50 bar in the higher and lower pipelines. The new MX valve type additionally has an integrated balancer cleaning gadget. It ensures that the balancer is totally flushed from the surface throughout seat lifting concurrently cleaning-in-place is going down. All surfaces involved with the product may be cleaned with none additional parts protecting the product from contamination.
