Diaphragm valve is a special form of shut-off valve, whose opening and closing component is a diaphragm made of soft material, which separates the valve body cavity from the valve cover cavity and driving components. It is widely used in various fields. The vacuum diaphragm valve adopts connection forms such as loose flange connection, quick release flange connection, and welded connection. Welded connections can be divided into welded Type I connections (i.e. welded at both ends) and welded Type II connections (i.e. welded at one end and inserted at the other end). The working medium suitable for vacuum diaphragm valves is air and non corrosive gases.

Below, the editor will briefly introduce the characteristics of vacuum diaphragm valves, as follows:

1. Can be used for media containing hard suspended solids; Due to the fact that the medium only comes into contact with the valve body and diaphragm, there is no need for a stuffing box, and there is no problem of stuffing box leakage, which may cause corrosion to the valve stem.

2. Cannot be used in high-pressure situations.

3. Low fluid resistance.

4. Suitable for corrosive, viscous, and slurry media.

Based on the above content, the editor hopes it will be helpful for everyone to understand vacuum diaphragm valves.
