How it works

The Alfa Laval Unique Mixproof Process valve is a normally closed (NC) valve controlled from a remote location by means of compressed air. The valve has two independent plugs and seals to separate the liquids; the space between the seals forms a leakage chamber at atmospheric pressure under every operating condition. Leakage rarely occurs, but  should it occur, the product flows into the leakage chamber and drains through the outlet at the bottom of the chamber for easy detection.

When the valve is open, the leakage chamber is closed. The product then flows from one line to the other. The well-known radial design of the valve ensures that virtually no product spillage occurs during valve operation.
