Manufacturers of food and different hygienically processed products face the challenge of maintaining reproducible processes in order that their products have the looks, style, and consistency that buyers expect.
GEA has designed the VARIVENT MX with elements that keep products from mixing with the cleaning liquid, even under exceptional loads. The cavity chamber is fitted with a vacuum self-drainage system and balancers on both valve discs. For maximum bodily safety, GEA makes use of the Venturi effect which is created by the special form of the move channels, inflicting a vacuum on the alternative seal during lifting, stopping pressure increases. As Professional , no cleaning liquid can enter the other pipe carrying the product while a valve seat is being lifted or cleaned, even when a seal is defective.
When new systems are set up and adjusted in a short while, there’s a greater danger of overpressure during operation. The valve discs must keep in place when water hammer happens, and the valve should stay closed. For this function, GEA has geared up the valve discs in each pipelines with balancers – strain compensators. This makes the closed valve resistant to water hammer up to 50 bar within the higher and lower pipelines. The new MX valve sort also has an integrated balancer cleaning device. It ensures that the balancer is totally flushed from the surface during seat lifting simultaneously cleaning-in-place is happening. All surfaces involved with the product can be cleaned without any extra components defending the product from contamination.
