VEOX PMO double independent plugs mix-proof valve

The new VEOX PMO mix-proof valve, with double independent plugs and no product loss when opening, meets the 3A recommendations (85-03) in accordance with dairy sanitary requirements. The physical break between two circuits allows two different liquids to flow through the valve without the risk of cross contamination.
