Manufacturers of food and other hygienically processed products face the problem of maintaining reproducible processes in order that their merchandise have the looks, style, and consistency that customers count on.
GEA has designed the VARIVENT MX with elements that maintain merchandise from mixing with the cleansing liquid, even under distinctive masses. The cavity chamber is fitted with a vacuum self-drainage system and balancers on both valve discs. For maximum physical safety, GEA makes use of the Venturi effect which is created by the particular form of the circulate channels, inflicting a vacuum on the alternative seal during lifting, preventing stress increases. As a outcome, no cleansing liquid can enter the alternative pipe carrying the product whereas a valve seat is being lifted or cleaned, even if a seal is flawed.
When new methods are arrange and adjusted in a short while, there is a larger threat of overpressure during operation. The valve discs must keep in place when water hammer happens, and the valve should remain closed. For this function, GEA has equipped the valve discs in both pipelines with balancers – stress compensators. This makes the closed valve proof against water hammer as much as 50 bar within the higher and decrease pipelines. The new MX valve kind also has an integrated balancer cleaning gadget. It ensures that the balancer is completely flushed from the surface throughout seat lifting simultaneously cleaning-in-place is taking place. pressure gauge octa involved with the product can be cleaned without any extra components defending the product from contamination.
