There are many parts of the sanitary diaphragm valve, including black metals and non -ferrous metals and alloys of various brands and various non -metal materials. Materials of the valve body, valve cover and valve board (valve petals): valve body, valve cover and valve petals are one of the main parts of the diaphragm valve, which directly tolerate the pressure of the medium. Regulation.

The materials for manufacturing sanitary diaphragm valve parts should be selected according to the following factors:

1. In the case of meeting the above conditions, there must be lower costs.

2. Use work conditions (pressure, temperature and characteristics of working medium).

3. The force of the parts and the effect of the structure of the diaphragm valve.

4. Have good craftsmanship.
