Sanitary Diaphragm Valve is widely used in sanitary industries such as food, beverage, pharmaceutical, cosmetics, and chemical industry. In these industries, there are high requirements for the cleanliness, corrosion resistance, and sealing performance of the equipment. It can meet these requirements, ensure the purity of the medium, and prevent the growth of microorganisms; it is mainly composed of valve body, valve cover, diaphragm, valve stem, handwheel and other components. The valve body and valve cover are made of stainless steel, and the surface is polished to ensure easy cleaning. The diaphragm is a key component of the valve. It is usually made of non-toxic, odorless, high temperature resistant, and corrosion resistant rubber or plastic materials. It can effectively isolate the medium from contact with the metal parts inside the valve body to prevent the medium from being contaminated. The valve stem and handwheel are made of stainless steel, which is easy to operate and has a long service life.

The sanitary diaphragm valve drives the valve stem up and down by rotating the handwheel, thereby changing the distance between the diaphragm and the valve seat to realize the opening and closing of the valve. When the valve is opened, the distance between the diaphragm and the valve seat increases, and the medium passes through the valve; when the valve is closed, the distance between the diaphragm and the valve seat decreases, and the medium is cut off. Due to the large sealing surface between the diaphragm and the valve seat, it has good sealing performance.

Advantages of sanitary diaphragm valves:

1. Easy to clean: The valve body and valve cover are made of stainless steel, and the surface is polished to ensure easy cleaning. In the food, beverage, pharmaceutical and other industries, the cleanliness requirements for equipment are very high, and it can meet the needs of these industries.

2. Corrosion resistance: The diaphragm is usually made of non-toxic, odorless, high temperature resistant, and corrosion resistant rubber or plastic materials, which can effectively isolate the medium from contact with the metal parts inside the valve body to prevent the medium from being contaminated.

3. Good sealing performance: Due to the large sealing surface between the diaphragm and the valve seat, it has good sealing performance and can effectively prevent the leakage of the medium.

4. Easy to operate: The valve stem and handwheel are made of stainless steel, which is easy to operate and has a long service life.

When selecting a sanitary diaphragm valve, the appropriate valve type and material should be selected according to the actual working conditions and the properties of the medium. At the same time, in order to ensure the normal operation of the valve and extend its service life, the valve should be inspected and cleaned regularly to ensure the cleanliness and sealing performance of the valve.
