Cost effective mixproof valve

Alfa Laval Unique mixproof valves feature two independent plugs, which means that a single Unique mixproof valve can often replace two or more valves of other types.

A state-of-the-art double-seat design provides long-lasting, spillage-free operation thus minimizing the risk of product contamination. The use of double lip seals provides added protection to ensure safe and hygienic operation.

Så fungerar det


Unique Mixproof-ventilkonceptet baseras på en serie baskomponenter, bland annat ventilhus, ventilplugg, styrdon samt tillval och tillbehör för rengöring som stöder många olika användningsområden. Med hjälp av dessa komponenter kan du skapa en Unique Mixproof-ventil som matchar dina exakta processkrav.

För att underlätta underhållet innehåller Unique Mixproof-ventilen även hål för läckagedetektering som gör att slitage eller skador på statiska o-ringar kan identifieras i tid. Operatörerna kan när som helst visuellt inspektera ventilen utan att behöva plocka isär den.


Alfa Laval Unique Mixproof-ventilen är en normalt sluten ventil som kan fjärrstyras med tryckluft.

För att separera de två vätskorna har ventilen två oberoende pluggtätningar. Utrymmet mellan de två tätningarna bildar en atmosfärisk läckagekammare. I sällsynta fall av oavsiktligt produktläckage, rinner produkten in i läckagekammaren och släpps ut genom läckageutloppet.

När ventilen är öppen är läckagekammaren stängd. Produkten kan sedan rinna från en ledning till den andra utan spill. Ventilen kan enkelt rengöras och skyddas mot följderna av tryckslag i enlighet med processens specifika krav och ventilens konfiguration. (Det spills ingen produkt när ventilen används).

SpiralClean system

Alfa Laval offers its external connected CIP system "SpiralClean". This system ensures hygienic operation in demanding applications where cleaning of the Unique Mixproof by seat lift and seat push function is not sufficient. The SpiralClean system can be added to clean the upper and lower plugs and to rinse the leakage chamber of the valve. Using less cleaning fluid, utilities and time, SpiralClean cleans more thoroughly and efficiently than conventional externally connected CIP devices.

Another big benefit: SpiralClean enables the Unique mixproof valve to operate under aseptic-like conditions, creating a steam barrier to the atmosphere upon applying steam to the CIP pipes.unique-mixproof-spiral-clean-640x360.png
