Top 7 Types of Sanitary Valves and Their Uses

A number of processing applications use sanitary valves to control the rate and flow of fluid transfer. Sanitary valves most often are used in food and beverage production, pharmaceuticals, biomedical products, chemical and petrochemical processing.

1. Air-Actuated Automatic Valves

Air-actuated automatic valves open and close the liquid flow path, allowing for metered flow in one or both directions. For most applications, this involves free flow from one direction and controlled, reduced flow in the other. The most common applications for these types of valves include chemical and petrochemical processing, water treatment plants, power plants and mining.

2. Shut Off Valves

A shut off valve works to safely control pressurized air in a pneumatic application. This allows operators to block compressed air in an industrial automation process and isolate systems when not in use. You will most often see sanitary shut-off valves n sanitary waste treatment, chemical processing, food and beverage production, and metal processing.

3. Diverter Valves

A diverter valve switches between different liquid flow paths, while preventing any backflow. Common applications include agriculture and farming, aviation and aerospace, chemical and petrochemical processing, food processing, pharmaceutical production, and sanitary waste processing.

4. Throttling Valves

A throttling valve aids in flow control, pressure control, filler-level control and modulated filling. These sanitary valves are a popular choice when your application requires the ability to start, stop, and regulate liquid flow. These types of sanitary valves are commonly used for food and beverage processing, dairy processing, and for producing personal care products.

5. Sanitary Check Valves

A sanitary check valve, also referred to as a “one-way valve,” controls flow in one direction only to prevent backflow. The most common applications for sanitary check valves are water treatment and reverse osmosis processes, food and beverage processing, chemical processing, and pharmaceutical production.

6. Ball Valves

A ball valve is ideal for preserving pressure levels throughout the fluid transfer process. Typical applications for sanitary ball valves include chemical processing, biopharmaceuticals, food and beverage production, and other personal care applications like lotions, soaps, and cosmetics.

7. Relief Valves

A relief valve releases excess pressure to prevent over-pressurizing the system. When a set pressure threshold is met at the valve seat, the valve will open. This type of sanitary valve is common in any process that uses compressed air, such as industrial automation systems.
