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 valve range
The Alfa Laval Unique mixproof valve concept provides modular solutions that you can easily tailor to your specific requirements. This means you only pay for the exact features and capabilities you really need. To make selection easier, a series of Unique Mixproof valve versions is available.
Unique Mixproof High Alloy
|Unique Mixproof High Alloy valve is developed and designed to suit tough applications within dairy, food, beverage, personal and home care applications. Products with high level of chloride, chemicals or low pH demand high grade alloy equipment to improve corrosion resistance.|
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.|
为方便维护，阿法拉伐独特的防混阀还具有泄漏检测孔，可预先告知静态 O 形圈的磨损或损坏情况。 操作员无需拆卸阀门，就可以随时直观地检查阀门。
打开阀门时，泄漏腔关闭。 此时产品可从一条管路流至另一条管路，而没有溢出。 根据具体的工艺和阀门配置的需要，该阀门可以轻松地清洁，并防止水锤的影响。 （阀门操作期间没有产品溢出）。
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.
