Manufacturers of food and other hygienically processed merchandise face the challenge of sustaining reproducible processes in order that their merchandise have the looks, style, and consistency that buyers anticipate.
GEA has designed the VARIVENT MX with components that maintain merchandise from mixing with the cleansing liquid, even underneath distinctive loads. The cavity chamber is fitted with a vacuum self-drainage system and balancers on both valve discs. For pressure gauge น้ำมัน , GEA makes use of the Venturi effect which is created by the particular shape of the move channels, inflicting a vacuum on the alternative seal during lifting, preventing pressure increases. As a outcome, no cleaning liquid can enter the opposite pipe carrying the product whereas a valve seat is being lifted or cleaned, even if a seal is defective.
When new systems are set up and adjusted in a quick while, there is a larger risk of overpressure throughout operation. The valve discs must stay in place when water hammer occurs, and the valve must stay closed. For this function, GEA has geared up the valve discs in both pipelines with balancers – pressure compensators. This makes the closed valve proof against water hammer up to 50 bar within the upper and decrease pipelines. The new MX valve type also has an integrated balancer cleansing device. It ensures that the balancer is completely flushed from the surface throughout seat lifting concurrently cleaning-in-place is happening. All surfaces in contact with the product can be cleaned with none further parts defending the product from contamination.
