Product detail

  • Product code
    Mixproof valves
  • APPLICATIONS
    Safe separation of different fluids in valve clusters to minimize space requirements.
 

Concept

The Unique Mixproof Valve is designed with user flexibility in mind. The customer can choose additional options as required individually; for example higher hygiene demands or higher resistance against physically tough conditions.

 

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 next page). There is virtually no spillage of product when operating the valve.

Automated level control

ThinkTop V50 and V70

The modular concept of these shut-off valves enables you to tailor them to your specific requirements and only pay for features and capabilities you need. You get the full benefit of the Unique Mixproof valves by combining them with Alfa Laval ThinkTop v70 sensing and control units.

Cost effective

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.

Maintain

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.

Valve clusters

Valve clusters - customized flow solutions 

We are specialists in providing pre-built valve clusters customized to meet specific, individual requirements.
