Tools is fitted with a vacuum self-drainage system and balancers on both valve discs. For maximum bodily security, GEA makes use of the Venturi impact which is created by the particular form of the move channels, causing a vacuum on the opposite seal during lifting, stopping strain will increase. As a result, no cleaning liquid can enter the alternative pipe carrying the product while a valve seat is being lifted or cleaned, even when a seal is defective.
When new systems are arrange and adjusted in a short time, there is a larger threat of overpressure during operation.

This makes the closed valve proof against water hammer up to 50 bar in the upper and decrease pipelines. The new MX valve kind additionally has an built-in balancer cleansing gadget. It ensures that the balancer is completely flushed from the skin during seat lifting simultaneously cleaning-in-place is taking place. All surfaces in touch with the product can be cleaned with none further components protecting the product from contamination.
