Unique Mixproof CP-3

The Alfa Laval Unique Mixproof CP-3 Valve is a versatile, highly efficient and lightweight valve for the safe and efficient management of fluids at intersection points in valve-matrix and piped systems. Based on the well proven and exceptionally versatile principle of the Unique Mixproof valves from Alfa Laval, it enables the simultaneous flow of two different products or fluids through the same valve without any risk of cross-contamination.

Highly efficient light-weight, reduced vent valve

Gentle product handling, enhanced product safety
Cost-effective, spillage-free operation
Optimized plant efficiency and enhanced cleanability
Leakage detection and leakage chamber cleaning
Fully configurable to fit your exact needs

The valve provides exceptional spillage-free operation and is compliant with most hygienic standards, including the 3-A Sanitary Standards, the Pasteurized Milk Ordinance and the seat lift requirements of the US Food and Drug Administration. With its modular design and a wide variety of options, the valve can be customized to meet any process requirement and provides low total cost of ownership. The valve maximizes available floor space while significantly minimizing downtime and consumption of Cleaning-in-Place (CIP) media. The Unique Mixproof CP-3 Valve is designed for continuous flow management in hygienic processes where product safety is at the top of the agenda. It is widely used across the dairy, food, beverage and many other industries.

Cost effective mixproof valve

Alfa Laval Unique Mixproof CP-3 features two independent plugs designed to be PMO compliant and meet the strict guides of 3A Sanitary Standard 85-03 ensuring the pressure in the leakage chamber is atmospheric or less during any working condition. Therefore, a single Unique Mixproof CP-3 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 CP-3 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.

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.

Valve clusters - customized flow solutions

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.

How it works

Construction

The unique mixproof valve concept is based on a series of base components, including valve body, valve plug, actuator and cleaning options and accessories that support a wide range of applications. Using these components, you can build a Unique mixproof valve to match your exact process requirements.

To facilitate maintenance, the Unique mixproof valve also features leakage detection holes that provide advance notification of wear or damage to static o-rings. Operators can visually inspect the valve at any time without having to disassemble it.

Operating principle

The Alfa Laval Unique mixproof valve is a normally closed (NC) valve that is controlled from a remote location by means of compressed air.

To separate the two liquids, the valve has two independent plug seals. The space between the two seals forms an atmospheric leakage chamber. In the rare case of accidental product leakage, the product flows into the leakage chamber and is discharged through the leakage outlet.

When the valve is open, the leakage chamber is closed. The product can then flow from one line to the other without spillage. The valve can easily be cleaned and protected against the effects of water hammer according to the specific requirements of the process and the configuration of the valve. (There is no product spillage during valve operation).

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 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.
