Unique mixproof valves enable the simultaneous flow of two different products or fluids through the same valve without risk of cross-contamination.
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.
Exceptional spillage-free operation
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.
Easy valve to maintain and clean
Unique mixproof valves feature a top-loaded design, making maintenance fast and easy. It also features no adjustable components, a maintenance-friendly actuator and built-in leakage detection on all seals. Unique mixproof valves meet most hygienic standards and can be supplied with the optional SpiralClean cleaning system.

Unique Mixproof UltraPure
|Unique Mixproof UltraPure valve is devolved and designed meet the stringent demands of the biotech- and pharmaceutical industries. This valve solution ensures a higher degree of plant flexibility resulting in optimized plant efficiency without compromising product safety. Customers have several options to fit individual needs; e.g. higher alloys to improve corrosion resistance. Like all our UltraPure equipment, Unique Mixproof UltraPure comes with the Alfa Laval Q-doc documentation package.|
Unique Mixproof Basic
|Unique Basic has the basic components that provide significant safety and leakage detection. It features an actuator without seat lift and unbalanced plugs.|
Unique Mixproof SeatClean
|Unique SeatClean is the choice for standard installations that handle products with solids. Seat lift during normal cleaning procedures cleans the plugs and seats. A balanced lower plug eliminates the risk of mixing products by pressure shock or when the pressure in the pipe is high.|
Unique Mixproof HighClean
|Unique HighClean meets your processing needs when dealing with sticky products. SpiralClean ensures thorough cleaning of the spindles, upper and lower plugs and in the leakage chamber. With balanced upper and lower plug, the configuration of this valve protects against the effects of high pressure and water hammer.|
Unique Mixproof UltraClean
|Unique UltraClean meets the highest demands for hygienic processing of sticky products, products with high content of solids, or applications that require close-to-aseptic conditions. It features an actuator with integrated seat lift, balanced upper and lower plugs and SpiralClean.|
O conceito da válvula Unique Mixproof é baseado em uma série de componentes de base, incluindo o corpo da válvula, plugue da válvula, atuador, opções de limpeza e acessórios que suportam uma ampla gama de aplicações. Usando esses componentes, você pode criar uma válvula Unique Mixproof para atender aos requisitos exatos do processo.
Para facilitar a manutenção, a válvula Unique Mixproof também possui orifícios de detecção de vazamento que fornecem notificação antecipada de desgaste ou danos nos O-rings. Os operadores podem inspecionar visualmente a válvula a qualquer momento sem precisar desmontá-la.
Princípio de funcionamento
A válvula Alfa Laval Unique Mixproof é normalmente fechada (NC) e controlada diretamente de um local remoto por meio de ar comprimido.
Para separar os dois líquidos, a válvula possui duas vedações de plugue independentes. O espaço entre as duas vedações forma uma câmara de vazamento atmosférico. No caso raro de vazamento acidental do produto, o produto flui para a câmara de vazamento e é descarregado através da saída de vazamento.
Quando a válvula estiver aberta, a câmara de vazamento estará fechada. Dessa forma, o produto pode circular de uma linha para a outra sem derramamentos. A válvula pode ser facilmente limpa e protegida contra efeitos de golpe de aríete de acordo com os requisitos específicos do processo e a configuração da válvula. (Não há derramamento de produto durante a operação da válvula.)
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.
