Alflow sells a wide range of mixproof valves for applications in the pharmaceutical and food industries. Mixproof valves prevent the mixing of two different products, e.g. a pharmaceutical product or a food and detergent. They are designed to meet the strictest hygiene requirements and come with full documentation.
Mixproof valves: Precise regulation, control and shut-off
Mixproof valves (double seat valves) are important in automatic processes where safe separation of crossing "hostile" fluids is required.
A mixproof valve replaces several single-seat or butterfly valves for the same task, resulting in a reduction in the required space and a reduction in installation and service costs. A mixproof valve can perform the same mixture safeguarding function as two single-seat valves.
The mixproof valve concept consists of two independently operating valve plugs, an atmospheric leakage chamber between the plugs and a leakage outlet for visual indication of leakage in the valve. The top and bottom plugs seal against two seats and safely separate two intersecting fluid lines. Leaking fluid from both lines will always flow into the leakage chamber and discharge through the leakage outlet.
A mixproof valve is used, e.g., in the beverage industry, the food industry and the pharma & biotech industry. For example, it is compatible with:
- Fat and oil
- Fruit and vegetable puree
- Beer and cider
- Tea and coffee
- Wine and spirits
- Soft drinks
- Ice cream
- Milk, cream and yoghurt
Our mixproof valves are extremely durable as they are made of high-quality stainless steel.
A successful mixproof-valve operation depends a lot on a correct valve selection. To ensure a correct mixproof-valve selection, it is important to include all necessary process and location data as well as customer preferences in the calculations.
The mixproof valves come with a steam barrier, which is recommended for highly hygienic applications such as sterile, aseptic processing or high-temperature sterilisation. The steam barrier, placed between the valve body and the pneumatic actuator and located on the lower shutter, allows safe separation between the product and the external atmosphere.
Mixproof valves with long-lasting solution
Do you work in the sanitary industry where there is a need for safe separation of intersecting "hostile" fluids? Then a mixproof valve from our range will definitely be of interest to you.
You can choose to have the valve delivered with the current certificates, which are suitable for several industries. For example, certificates such as:
- USP Class VI
At Alflow, we also want to supply the best valves on the market. You can see this, e.g., by the fact that our models are extremely durable, as they are produced in the most suitable material in terms of application possibilities. By purchasing valves from Alflow, you get a long-lasting solution.
We have a wide selection of mixproof valves – including bottom valves and PMO valves for sanitary process systems. The Mixproof bottom valve is designed for installation in the tank bottom and the PMO valve meets the US PMO (Pasteurized Milk Ordinance) regulations.
Common to all our mixproof valves is that they are designed to meet the strictest hygiene requirements and that they are easy to maintain without the use of special tools. The mixproof valves are sanitary, mixture resistant valves in a modern and compact design, machined from bar steel and always in stainless steel.
Did you know that we also offer thorough servicing of valves? With a mixproof valve from our range, your piping systems are guaranteed reliable operation and tight seal - both at high and low temperatures.

What is a mixproof valve?
Mixproof valves (double seat valves) work by means of two valve plugs sealing independently against two seats and safely separating two crossing fluid lines. A mixproof valve can perform the same mixture-resistant function as two single-seat valves and is used in automatic processes where safe separation of crossing "hostile" liquids is required.
