What is a sanitary diaphragm valve?

VDN series sanitary diaphragm valves are suitable for flow control and switch operation in food, beverage, dairy, brewing and pharmaceutical industries. This valve uses a diaphragm as a fluid barrier and regulates fluid flow by controlling the opening and closing of the diaphragm.

Characteristics of sanitary diaphragm valve:

1.Sanitary materials: The materials of the valve must meet food grade or pharmaceutical grade standards to ensure that the fluid is not contaminated and meets the sanitation standards.

2.No dead angle design: The precise valve design avoids dead angles or accumulation of fluid inside, reducing the risk of bacterial growth.

3.Easy to clean: The valve surface is smooth, which is convenient for cleaning and disinfection to ensure product safety and hygiene.

4.Reliable sealing: The diaphragm valve uses a diaphragm as the valve seat, and the pressure controls the opening and closing to ensure reliable sealing performance.

5.High controllability: The opening and closing of the diaphragm valve can be achieved through a manual or automatic control system, with excellent controllability.

The Application Field of Sanitary Diaphragm Valve:

1.Food manufacturing industry: Sanitary diaphragm valves are widely used in food, wine, beverage, dairy products and other production processes due to their simple structure, convenient loading and unloading, flexible operation, and low fluid resistance. They are used to control the flow of water, gas, finished oil and corrosive media.

2.Biochemical pharmaceutical industry and biotechnology: In these industries, the anti-pollution performance of sanitary diaphragm valves is particularly important. A closed space is formed inside the valve to prevent the fluid in the pipeline from mixing with air, dust and impurities in the environment, thereby preventing contamination and cross infection.

3.Fine chemicals and bioengineering: Sanitary diaphragm valves can adapt to a variety of media, including gas, liquid, high-viscosity fluid, etc., so they are also widely used in these industries.
