State-of-the-art horizontal mixproof valve
Based on the well proven and exceptionally versatile principle of the Unique Mixproof valves, this horizontal mixproof tank valve features many of the same components, such as the actuator, yoke and seals, and therefore the same spare parts. This provides the benefits of easy serviceability and low total cost of ownership.
Alfa Laval Unique Mixproof Horizontal Tank Valve, can be fitted with any level of sensing and control. It is as standard supplied with seat lift, which enables handling of two different products at the same time, or safe handling of one product while seat-lift cleaning operations are being conducted in the other portion of the valve – all without any risk of cross-contamination. The double tangential design of the valve body ensures full drainability, especially when the valve is mounted at the bottom of a flat-bottomed tank.
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.
Valve clusters – customized flow solutions
We are specialists in providing pre-built valve clusters customized to meet specific, individual requirements.
Our expertise helps ensure you the most efficient flow management, using as few components as possible and dealing effectively with key issues that include thermal cycling, cleanability, drainability and flow control.
Alfa Laval valve clusters can be supplied pre-assembled and pre-tested as well as fully wired and with all the necessary pneumatic tubing, junction boxes and control panels pre-connected.
This means you can bring even complex installations online as quickly as possible, saving time and avoiding lost revenue associated with on-site troubleshooting and downtime.

How it works
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.
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).
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 cleaning devices. All external CIP systems 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.
Unique Mixproof Horizontal Tank Valve
The Unique Mixproof HT valve provides a state of the art solution when there is no CIP pressure or flow from the tank side to clean the seat and plug. The valve is self-cleaning, thanks to two Cleaning-in-Place (CIP) nozzles. The first nozzle is designed specifically for plug cleaning. This double-acting nozzle projects cleaning solution through the tank connection, ensuring complete cleaning of the seat contact surfaces as well as the shadow area of the tank port.
The second is a rotating CIP nozzle incorporated into the unit for optimum cleaning of the full-bore leakage chamber. The design of the single valve body makes it suitable to weld directly on the tank or to connect it via a Tri-clamp.
The 4” and 6” models feature a 45-mm opening, which enables the passage of very large particles or efficient handling of high viscosity fluids.
