What Are The Working Characteristics Of Sanitary Diaphragm Valves?

There is a diaphragm between the valve body and the valve cover of Sanitary Diaphragm Valve. The diaphragm is made of rubber or polytetrafluoroethylene. When the diaphragm moves up and down, it adjusts the flow through the valve. So do you know what are the working characteristics of sanitary diaphragm valves?

Working characteristics of sanitary diaphragm valves:

1. Simple structure and few parts The diaphragm valve is composed of only three main parts: valve body, diaphragm and valve cover assembly.

2. Easy to disassemble and repair Generally, the damaged part of the diaphragm valve is the diaphragm. When replacing the diaphragm, there is no need to remove the valve from the pipeline. Just remove the valve cover. The replacement of the diaphragm can be completed on site in a short time

3. Good sealing performance Since the diaphragm is made of soft materials such as rubber or plastic, it has good sealing, but the mechanical life of the diaphragm is short.

4. There is no dead angle in the valve. The valve body flow channel is streamlined, the flow channel is smooth, and there is no dead angle. The medium flowing through the valve cannot be deposited in the valve and moldy and deteriorated, and it is easy to flush. The medium flowing through will not get stuck if it contains fibers or particles.
5. Packingless diaphragm valve does not need packing and is non-corrosive to the valve stem and valve cover (because the diaphragm separates the lower valve body from the inner cavity of the upper valve cover)
6. Wide application, can be used for cutting and throttling
7. Corrosion resistance Due to the diversity of lining, it has good chemical resistance.

Sanitary diaphragm valve has the advantages of simple structure, beautiful shape, quick disassembly and assembly, flexible operation, small fluid resistance, and reliable use.
