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.Unique Mixproof exploded view w ThinkTop V70_600x375.jpg

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).
