Manufacturers of food and different hygienically processed merchandise face the problem of sustaining reproducible processes so that their products have the looks, style, and consistency that customers anticipate.
GEA has designed the VARIVENT MX with elements that keep products from mixing with the cleansing liquid, even beneath 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 effect which is created by the particular form of the move channels, inflicting a vacuum on the other seal throughout lifting, preventing pressure increases. As a end result, no cleansing liquid can enter the other pipe carrying the product whereas a valve seat is being lifted or cleaned, even when a seal is defective.
When new techniques are arrange and adjusted in a short time, there is a larger danger of overpressure throughout operation. The valve discs should stay in place when water hammer happens, and the valve must stay closed. For this purpose, GEA has equipped the valve discs in both pipelines with balancers – pressure compensators. This makes the closed valve immune to water hammer up to 50 bar in the upper and decrease pipelines. The new MX valve type additionally has an integrated balancer cleansing gadget. เกจวัดแก๊สหุงต้ม ensures that the balancer is completely flushed from the outside throughout seat lifting simultaneously cleaning-in-place is going down. All surfaces involved with the product can be cleaned with none further components defending the product from contamination.
