What are Sanitary Valves?

Sanitary valves are essential components used in various industries such as food and beverage, pharmaceuticals, and biotechnology. These valves ensure that the process is sterile, safe, and high quality. They are designed to meet the strict requirements of these industries, with the goal of preventing contamination or cross-contamination.

Sanitary valves are made from high-quality materials like stainless steel and are designed to be easy to clean and maintain. They come in different types, such as ball valves, butterfly valves, and diaphragm valves. Each has its own unique properties and usage, depending on the industry and the specific process.

Sanitary valves play a crucial role in maintaining the integrity of the process. They prevent any external factors from contaminating the process and ensure that the product is safe for consumption or use. Sanitary valves also prevent the growth of bacteria and other microorganisms that can cause harm.

How do Sanitary Valves Work?

Sanitary valves work by controlling the flow of fluids through a pipeline. The valve consists of a body, a disc, and a stem. The disc moves inside the body to regulate the flow of the fluid. The stem is connected to the disc and is used to control the movement of the disc. When the stem is turned, the disc opens or closes, allowing or restricting the flow of the fluid.

Where are Sanitary Valves Commonly Used?

Sanitary valves are widely used in various industries that require strict hygiene standards including pharmaceuticals, food and beverage, biotechnology, cosmetics, and dairy.

In the food and beverage industry, sanitary valves are used to control the flow of liquids and gases in production, packaging, and storage. They are commonly used in dairy processing plants for milk, cream, and yoghurt, as well as in breweries for beer and wine production.

Pharmaceutical companies use sanitary valves in the manufacture of drugs, vaccines, and medical devices to prevent contamination and ensure safety. These valves are critical in maintaining the sterile environment required for the production of pharmaceutical products.

Biotechnology and cosmetics industries also use sanitary valves to control the flow of products during processing and packaging. Sanitary valves are designed to meet the strict regulations of these industries, ensuring that the products are safe and free from contaminants.

Choosing the Right Sanitary Valve for Your Application?

When it comes to selecting a sanitary valve, factors such as the type of fluid, temperature, pressure, and flow rate must be considered. It is also important to take into account the material used to manufacture the valve, as this can impact durability, corrosion resistance, and overall performance.

Sanitary valves come in different types, including ball valves, butterfly valves, diaphragm valves, and check valves. Each type has its unique features and advantages, making them suitable for different applications. 

In addition to the type of valve, the size and connection type must also be considered. Sanitary valves typically come in standard sizes, and it is essential to choose the right size to prevent issues such as flow restriction and pressure drop.

What Type of Sanitary Valves are Available?

Firstly, there are ball valves, which are versatile and commonly used in the food, beverage, and pharmaceutical industries. They have a simple design and are easy to clean and maintain.

Secondly, butterfly valves are suitable for large pipelines and are commonly used in the dairy industry. They have a low profile and don’t take up much space, making them ideal for tight spaces.

Thirdly, diaphragm valves are suitable for applications that require a high level of control and precision, such as biotech and pharmaceutical industries. They are also easy to clean and maintain.

Fourthly, check valves are used to prevent backflow in piping systems and are commonly used in the food and beverage industry. They are simple in design and easy to install.

Lastly, globe valves are used for regulating flow and are commonly used in sanitary applications that require precise control over flow rates. They are ideal for high-pressure applications and are commonly used in the pharmaceutical and biotech industries.

It’s important to consider the specific needs of your industry and process when selecting a sanitary valve type. By selecting the right valve, you can ensure optimal performance and efficiency in your operations.

What are the Advantages and Disadvantages of Using a Sanitary Valve?


Prevent Contamination: Sanitary valves are designed to prevent contamination during the manufacturing process. They are made of materials that are easy to clean, sanitise, and sterilise. As a result, they reduce the risk of bacterial growth, viruses, and other contaminants.

Maintain Hygiene: Sanitary valves are designed to maintain hygienic conditions during the manufacturing process. They prevent the build-up of bacteria and other harmful contaminants that can cause health issues.

Durability: Sanitary valves are durable and can withstand harsh chemicals, high temperatures, and high-pressure applications. They are made of materials that can withstand corrosion, wear and tear, and extreme stress.

Easy to Maintain: Sanitary valves are easy to maintain and can be quickly disassembled, cleaned, sanitised, and reassembled. They require minimal maintenance, reducing downtime and increasing productivity.


Cost: Sanitary valves are more expensive than traditional valves due to their specialised design and materials. The cost of purchasing and maintaining them can be high, especially for small businesses.

Complexity: Sanitary valves are more complex than traditional valves, which can make them challenging to install, maintain, and repair. They may require specialised knowledge and equipment to operate and repair.

Limited Applications: Sanitary valves are designed for specific applications and industries, such as food and beverage, pharmaceuticals, and cosmetics. They may not be suitable for other industries or applications.

Size Limitations: Sanitary valves are typically smaller than traditional valves, which can limit their flow rate and capacity. They may not be suitable for high-capacity applications.


In conclusion, sanitary valves may not be the most glamorous topic, but they play a crucial role in keeping our food and beverage industry safe and hygienic. With their ability to prevent contamination and ensure product quality, they are a must-have for any company in the industry. 

So, the next time you enjoy a refreshing beverage or a delicious meal, remember the unsung hero that helped make it possible: the sanitary valve.
