Sanitary valves come in several types, each with unique characteristics and uses. Butterfly valves, for instance, are known for their simple design and cost-effectiveness. They consist of a disc positioned in the center of the pipe and a rod passing through the disc to an actuator on the outside. When the actuator is turned, the disc either allows the fluid to flow through or blocks it off. This type of valve is commonly used in large-diameter pipes in the food and beverage industry. Ball valves are another type of sanitary valve. They utilize a ball with a hole through its center that can be aligned with the pipe to allow flow or perpendicular to it to block flow. Ball valves provide excellent sealing and are easy to operate, making them suitable for both on/off and throttling applications.

Diaphragm valves, on the other hand, use a flexible diaphragm to control flow. The diaphragm is moved by a handle or actuator, pushing it down onto a weir (or saddle) to block flow or lifting it up to allow flow. These valves are widely used in biopharmaceutical applications due to their superior sealing capabilities and ability to handle high-purity and corrosive fluids. Check valves, also known as non-return valves, are designed to allow fluid to flow in one direction only. They prevent backflow, thus protecting equipment and processes from potential damage or contamination. Lastly, there are also sample valves, which are used to take samples of the medium in a sanitary manner, ensuring that the process remains uncontaminated. Each of these sanitary valves plays a crucial role in maintaining hygiene standards in industries where cleanliness and sterility are paramount.

How they work and their unique features.

Sanitary valves function by managing the flow of fluids or gases within a system. They are designed to open, close, or partially obstruct various passageways, which can be controlled manually or automatically depending upon the system requirements. Butterfly valves, for instance, have a disc positioned in the center of the pipe. When the actuator is turned, it rotates the disc either parallel or perpendicular to the flow, thus regulating it. These valves are compact and cost-effective, making them suitable for large-diameter pipes. Ball valves feature a ball with a hole through its center. Depending on the position of the hole—aligned with the flow or perpendicular to it—the valve allows or blocks the fluid. Known for their excellent sealing capabilities, they are great for both on/off and throttling applications.

Diaphragm valves use a flexible diaphragm to control flow. The diaphragm moves up and down against a weir, allowing or blocking the flow. They offer superior sealing capabilities and are ideal for handling high-purity or corrosive fluids, often used in biopharmaceutical applications. Check valves, on the other hand, only allow fluid to flow in one direction, preventing backflow and protecting equipment from potential damage. They automatically respond to changes in pressure or direction of the fluid flow. Lastly, sample valves are uniquely designed to extract samples of the medium without contaminating the process. Each sanitary valve type boasts unique features that make them indispensable in industries where high hygiene standards are mandatory.
