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
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.
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).
