Alfa Laval Unique Mixproof 3-Body Valves enable the simultaneous flow of two different products or fluids through the same valve without risk of cross-contamination. The valve is also changeover function.
The Unique Mixproof 3-Body valve provides optimal process flow, outstanding hygiene, maximum uptime and low total cost of ownership. Its modular, three-valve body design provides reliable fluid handling and safety, making it perfect to use as a changeover valve for hygienic applications. This translates into substantial savings and efficiency gains.
Application
The Alfa Laval Unique Mixproof 3-Body is designed for continuous flow management and process safety in hygienic processes where product safety is at the top of the agenda across the dairy, food, beverage and a variety of industries.
Standard Design
The Alfa Laval Unique Mixproof 3-Body Valve is compromised of a series of base components, including valve body, valve plug, actuator, and cleaning options and accessories that support a wide range of applications. There are four pre-configured versions; the Unique Mixproof Basic; the Unique Mixproof SeatClean Valve; and the Unique Mixproof UltraClean Valve. Leakage detection holes enable visual inspection without requiring valve disassembly and provide advance notification of parts wear. Few straightforward moveable parts contribute to reliable operation and reduced maintenance costs. The valve can also be fitted with the Alfa Laval ThinkTop V50 and V70 for sensing the control of the valves.
Operating Principle
The Alfa Laval Unique Mixproof 3-Body Valve has a normally closed (NC) mixproof seat and a normally open (NO) single seat. The valve 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 the upper body section to the middle body section without spillage.
When the valve is closed, the leakage chamber is open. The product can flow from the lower body section to the middle body section without spillage.
The valve can easily be cleaned and protected against the effects of water hammer according to the specific process requirements and valve configuration. There is no product spillage during operation.
Cost Effective Mixproof Valve
Get exceptional results and save money. Replace two or more valves of other types with a single Alfa Laval Unique Mixproof 3-Body Valve. Two independent plugs and the fully balanced design enable two different fluids to pass through the same valve without risk of cross-contamination even in the event of pressure shock.
Exceptional Spillage-Free Operation
Enjoy long-lasting, spillage-free operation. To ensure safe and hygienic operation, the double-seat design avoid cross-contamination while the double lip seals provide added protection.
Easy to clean and maintain
Maintenance and cleaning are quick and easy due to a top-loaded design, no adjustable components, maintenance-friendly actuator and built-in leakage detection on all seals. The Unique Mixproof 3-Body valves is always equipped with seal lift and seat push function hence meets stringent hygienic standards.
Easy to configure and upgrade
Optimize your hygienic process by customizing the Alfa Laval Unique Mixproof 3-Body to suit your needs. Its modular design also makes it easy to apply the double seat valve whenever your process needs change while ensuring efficient, hygienic and continuous production.
Construction
The Alfa Laval Unique Mixproof 3-Body 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 build a Unique Mixproof 3-Body Valve to match your exact process requirements.
To facilitate maintenance, the Alfa Laval Unique Mixproof 3-Body 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.
SpiralClean System
To ensure the hygienic operating condition of its Unique Mixproof Valve range, Alfa Laval offers its SpiralClean system to clean the outside of upper and lower balancers of the valves. Alfa Laval SpiralClean uses less cleaning fluid utilities and time; it is recommended for use is processes with a high content of dry matter. All external CIP devices for Unique Mixproof Valves include the SpiralClean design as standard.
Another big benefit: SpiralClean enables the Unique Mixproof Valve to extend product shelf life.
