Unique Mixproof Tank Outlet

Same basic advantages as the unique mixproof valves but specially designed for mounting directly on the tank wall at the inlets and outlets. For tank inlet and outlet applications, the Unique mixproof tank outlet (TO) valve offers full drainability and provides cleanability all the way up to the tank without any risk of cross-contamination.

Cost effective tank outlet mixproof valve

Alfa Laval Unique Mixproof TO valves feature two independent plugs. It is the choice for hygienic installations enabling safe filling or emptying of tanks.

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 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.

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).

SpiralClean system

To ensure the hygienic operating condition of its Unique mixproof valve range, Alfa Laval offers its SpiralClean system to clean the upper and lower balanced plugs and leakage chamber of the valves. Using less cleaning fluid, utilities and time, SpiralClean cleans more thoroughly and efficiently than conventional externally connected CIP devices. All external CIP devices for Unique mixproof valves include the SpiralClean design as standard.

Another big benefit: SpiralClean enables the Unique mixproof valve to operate under aseptic-like conditions, creating a steam barrier to the atmosphere upon applying steam to the CIP pipes.
