Mixproof valves
Alflow offers a wide range of mixproof valves for applications in the pharmaceutical and food industries. Mixproof valves prevent mixing of two different products, e.g. a pharmaceutical product or a food and cleaning fluid. They are designed for 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 automated processes where there is a need for safe separation of crossing "hostile" fluids.
A mixproof valve replaces multiple single-seat or butterfly valves for the same task, resulting in a reduction of space required and reduction in installation and service costs. One mixproof valve can perform the same mixproof function as two single-seat valves.
The mixproof 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 upper and lower plugs seal against two seats and safely separate two intersecting fluid lines. Leaking fluid from both lines will always flow into the leak chamber and discharge through the leak outlet.
A mixproof valve is used in the beverage industry, food industry and pharma & biotech industry, among others. For example, it is compatible with:
- Grease and oil
- Gelatine
- Chocolates
- Fruit and vegetable puree
- Beer and cider
- Tea and coffee
- Wine and spirits
- Soft drinks
- East
- Is
- Milk, cream and yoghurt
Our mixproof valves are extremely durable as they are produced in solid stainless steel bars.
A successful mixproof valve operation depends heavily on correct valve selection. To ensure correct mix-proof valve selection, it's important to include all necessary process and site data as well as customer preferences in the calculations.
The Mixproof valves are available with a vapour barrier, which is recommended for highly hygienic applications such as sterile, aseptic processing or high temperature sterilisation. The vapour 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.

What is a mixproof valve?
Mixproof valves (double-seat valves) work by using two valve plugs that independently seal against two seats and safely separate two crossing fluid lines. A mixproof valve can perform the same mix-proof function as two single-seat valves and is used in automated processes where safe separation of crossing "hostile" fluids is needed.
