The chemical manufacturing industry generally uses a valve with a flow passage that is directly connected, and its fluid density is small. It is usually selected as a valve for closing and opening the medium to the outside, and a valve that is easy to adjust the total flow is used for adjusting the total flow. Plug valves and The valve is more suitable for phase commutation separation, and the valve with the scrubbing effect is best suitable for the medium containing floating particles.
Common chemical plant valves include valves, globe valves, globe valves, valves, plug valves, globe valves, etc. Chemical plant valve media commonly contain compounds, and there are many kinds of corrosive media containing strong acids and strong alkalis. At the material level, the core 304L and 316 are dominant. Generally, 304 should also be selected as the core raw material for the general medium. Choose carbon steel or fluorine-lined valves.
