Unique Mixproof UltraPure Valves


Harco offers the Alfa Laval Unique Mixproof UltraPure Valves, designed to suit the needs of the pharmaceutical and biotech industries. It enables the simultaneous flow of two different fluids without the risk of cross-contamination. Modular in design, they ensure maximum uptime for continuous, high-purity processes.

Alfa Laval’s Unique Mixproof UltraPure 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 Alfa Laval Unique Mixproof UltraPure Valve to match your exact process requirements. The valve can also be fitted with the Alfa Laval ThinkTop V50 and V70 for sensing and control of the valve

The Unique Mixproof UltraPure Valves from Alfa Laval has two independent plug seals to separate the liquids; the space between the seals forms a leakage chamber under atmospheric pressure during every working condition. Leakage rarely occurs but, should it occur, product flows into the leakage chamber and exits through the bottom outlet for easy detection.

To facilitate maintenance, the Alfa Laval Unique Mixproof UltraPure 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.
