Manufacturers of food and other hygienically processed products face the challenge of maintaining reproducible processes so that their products have the looks, taste, and consistency that customers expect.
GEA has designed the VARIVENT MX with components that hold products from mixing with the cleansing liquid, even under exceptional loads. The cavity chamber is fitted with a vacuum self-drainage system and balancers on both valve discs. For most physical safety, GEA makes use of the Venturi impact which is created by the special form of the circulate channels, causing a vacuum on the alternative seal during lifting, stopping pressure increases. As a 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 systems are arrange and adjusted in a short time, there is a larger threat of overpressure throughout operation. digital pressure gauge should stay in place when water hammer happens, and the valve should stay closed. For this purpose, GEA has equipped the valve discs in both pipelines with balancers – pressure compensators. This makes the closed valve proof against water hammer as much as 50 bar within the higher and lower pipelines. The new MX valve type also has an built-in balancer cleansing gadget. It ensures that the balancer is totally flushed from the surface during seat lifting concurrently cleaning-in-place is happening. All surfaces in contact with the product may be cleaned with none extra components protecting the product from contamination.
