Vacuum diaphragm valve main parts selection method introduction

Vacuum diaphragm valves have many parts, including various grades of ferrous and non-ferrous metals and their alloys, and various non-metallic materials. The material used to make the diaphragm valve parts is selected according to the following factors:

1. Working conditions (pressure, temperature and characteristics of the working medium).

2. The force of the part and its function in the diaphragm valve structure.

3, has a good process.

4. Under the above conditions, there must be lower costs. Material of valve body, bonnet and valve plate (valve): The valve body, bonnet and valve disc are one of the main parts of the diaphragm valve. They directly withstand the medium pressure. The materials used meet the requirements of “pressure and temperature class of diaphragm valve”.
