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.
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.
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 standard configurations is available:
Unique Basic has the basic components that provide significant safety and leakage detection. It features an actuator without seat lift and unbalanced plugs.
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 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 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.
Unique Mixproof Tank Outlet is the choice for standard tank installations. Seat lift during normal cleaning procedures cleans the plugs and seats. A balanced plug protects against water hammer when closing in the direction of product flow.
Unique Mixproof Horizontal Tank Outlet Valve specially designed for horizontal mounting directly on the tank wall. It improves cleanliness of the horizontal tank connections and ensures that no area of the tank inlet or tank outlet is left uncleaned. The valve insures 100% drainability of the tank and for the 4'' and 6'' it offers the ability to handle particles up to 45 mm.
Unique Mixproof Large Particle Valve. For applications with very large particles or highly viscous fluids, this valve offers the same basic advantages as Unique mixproof valves but are specially designed with large openings up to 45 mm in diameter.
You get the full benefit of using Unique mixproof valves by combining them with Alfa Laval ThinkTop and ThinkTop Basic valve sensing and control units.
We are specialists in providing pre-built valve clusters customized to meet specific, individual requirements.
Our expertise helps ensure you the most efficient flow management, using as few components as possible and dealing effectively with key issues that include thermal cycling, cleanability, drainability and flow control.
Alfa Laval valve clusters can be supplied pre-assembled and pre-tested as well as fully wired and with all the necessary pneumatic tubing, junction boxes and control panels pre-connected.
This means you can bring even complex installations online as quickly as possible, saving time and avoiding lost revenue associated with on-site troubleshooting and downtime.
