The GEA Varivent MX mix-proof double-seat valve has been designed 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 disks. For maximum physical safety, GEA makes use of the Venturi effect: This is created by the special shape of the flow channels, which causes a vacuum on the opposite seal during lifting, preventing pressure increases.
