Mixproof Valves

Mixproof Valves

Mixproof valves are a crucial component in modern processing systems, particularly in the food and beverage industry. These valves are designed to prevent cross-contamination between two different product streams, ensuring optimal hygiene and safety standards.

How mixproof valves work 

The operating principle of a mixproof valve is that it creates a barrier between two product streams. This is achieved using two separate valve discs, which are situated within a single valve body. When the valve is closed, each disc seals against its corresponding seat, effectively separating the two product streams. The area between the discs is then cleaned using a CIP (clean-in-place) system, which ensures that any residue or contaminants are removed before the valve is opened again. 

Mixproof valves are often used in processes where different products are handled simultaneously, such as cream and milk in a dairy processing plant. Without a mixproof valve, these products would mix, leading to an inferior end product and potential food safety violations. However, by using a mixproof valve, each product stream can be isolated and processed separately, resulting in a higher-quality product. 

 Mixproof valves come in several types of models, including air-operated, manual, and automated valves. Air-operated mixproof valves are the most common, as they provide a reliable and efficient method of opening and closing the valve. Manual mixproof valves require a physical operator to open and close the valve, while automated valves can be operated remotely, either through a control panel or a computer system.  

Advantages of mixproof valves 

The mixproof valve has become a standard of its own in the food and beverage industry, due to the valve's many benefits and advantages, these include: 

Prevention of cross-contamination: Mixproof valves create a physical barrier between two different product streams, preventing even small amounts of contamination that could have serious consequences in industries such as food and beverage. 

Improved efficiency: Mixproof valves allow for multiple products to be handled simultaneously, increasing throughput, and reducing downtime. They can also be cleaned quickly and easily using CIP systems, further improving overall efficiency. 

Versatility: Mixproof valves can be customized to suit specific processing needs, with a variety of types available including air-operated mixproof valves, manual and automated mixproof valves. This allows for the right type of valve to be chosen to fit process requirements and level of automation.  

Reliability and durability: Mixproof valves are constructed from high-quality materials that are resistant to corrosion and wear, ensuring that they can withstand even the most demanding processing environments. This means that they are highly dependable, reliable, and durable over the long term. 

Industries and applications that USE mixproof valves 

Mixproof valves are mostly found in processing applications in the food and beverage industry. However, this is far from the whole truth. Mixproof valves are widely used in industries and applications where cross-contamination prevention is essential. Mixproof valves are also used in industries that handle very sensitive products, these include: 

Pharmaceutical industry: In the pharmaceutical industry, mixproof valves are used to prevent contamination between different drug products. They are commonly found in drug manufacturing facilities, as well as in hospitals and research labs. 

Cosmetics industry: Mixproof valves are also used in the cosmetics industry, where they prevent cross-contamination between different product streams. They are commonly found in facilities that manufacture sink care products, hair care products, and makeup. 

Chemical processing industry: Micproof valves are used in the chemical industry to prevent the mixing of incompatible chemicals 

Water treatment: Mixproof valves are used in water treatment facilities to prevent cross-contamination between clean and contaminated water. They are commonly used in municipal water treatment plants, as well as in industrial water treatment facilities.  

Food and beverage industry: Mixproof valves are used extensively in the food and beverage industry, where the prevention of cross-contamination between different product streams is extremely important. They are commonly found in dairy processing plants, breweries, wineries, and soft drink bottling plants, among others. 

Important considerations when selecting mixproof valves 

Selecting the right mixproof valve is a critical decision that will impact the performance, efficiency, and safety of your processing system. Some of the most important considerations include: 

Valve type: There are many different types of mixproof valves available, including air-operated, manual, and automated mixproof valves. Consider which type of valve best fits your process requirements and level of automation or use the contact form below and we will guide you to the best solution.   

Size and capacity: It’s important to choose a mixproof valve that is the right size and capacity for your specific processing needs. This includes the flow rate, pressure, and temperature of the fluid that will go through the valve. 

Materials of construction: The material used to construct mixproof valves is critical to their performance and durability. The material of the valve needs to be compatible with the products and cleaning agents used in the processing system, as well as their resistance to wear, corrosion, and other forms of damage. 

Hygiene and cleanability: Hygiene and cleanability are crucial considerations when selecting mixproof valves, especially in industries such as food and beverage where strict hygiene standards are enforced. This means that the valve should be easy to clean and sanitize, with a smooth surface and minimal dead space where bacteria can grow. 

Compliance: Compliance with industry standards and regulations is an important consideration when selecting a mixproof valve. The valves should be compliant with the relevant industry standards such as FDA, EHEDG, and 3-A to ensure that the mixproof valve meets the highest hygiene and safety standards.
