Introduction to Sanitary Diaphragm Valve
A sanitary diaphragm valve is a type of valve commonly used in industries where hygiene and cleanliness are of utmost importance, such as the food and beverage, pharmaceutical, and biotechnology industries. It consists of a valve body, a diaphragm, and an actuator. The diaphragm acts as a flexible barrier that separates the flow medium from the valve’s operating mechanism. When the actuator is activated, the diaphragm either moves up to allow the flow of fluid or moves down to block the flow. This design ensures that the fluid does not come into contact with the internal parts of the valve, preventing contamination and facilitating easy cleaning and sterilization.
