Alfa Laval Unique Mixproof valves enable simultaneous flow of two products or fluids through the same valve without risk of cross-contamination. Their exceptional spillage free operation is compliant with most hygienic standards.
Concept
The exceptional concept of this mixproof valve is characterized by excellent unmatched flexibility – yet still being very simple. The reliable modular design gives you the perfect valve for your exact needs in all mixproof operations with two different products flowing through one valve. Unique fits to your process! The unique quality of this mixproof valve is the system of combining specific features and functions from a great variety of options offered. It is exceptional to the world of mixproof valves, yet providing minimal service and maintenance.
Working Principle
Unique is remote-controlled by means of compressed air. The valve is a normally closed (NC) valve. The valve has two independent plug seals, forming a leakage chamber between them under atmospheric pressure during every working condition. In case of rare accidental leaking of product, this will flow into the leakage chamber and be 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. The valve can be cleaned and water hammer protected to any level according to the needs in the specific process (see fig. 2). There is virtually no spillage of product when operating the valve.
SpiralClean
The Unique concept offers the Alfa Laval SpiralClean system to clean the upper and lower balanced plugs and leakage chamber, helping to meet the high hygienic standards of the sanitary flow industry. The system cleans more efficiently, uses less cleaning fluid by ensuring that a directional flow of CIP fluid reaches all the surfaces in much less time
than with conventional systems. All external CIP systems for Unique includes the SpiralClean design as standard. Another benefit from the SpiralClean system is that it allows the Unique Mixproof valve to run under aseptic-like conditions. If you apply steam to the CIP pipes, this will form a steam barrier to the atmosphere.
Options
The concept of Unique is centering round the customer’s needs and provides modern tailor-made solutions which are secured for the future. The customer gets exactly what he needs and only that. Only Alfa Laval offers the possibility of not choosing unnecessary features and functions, thus avoiding problems caused by a non-adapted product.
