How to choose valves in chemical industry
Acetic acid: it is one of the more corrosive substances in organic acids. Ordinary steel will be seriously corroded in acetic acid at all concentrations and temperatures. Stainless steel is an excellent acetic acid resistant material. 316 stainless steel containing molybdenum can also be used for high temperature and dilute acetic acid steam. For high temperature and high concentration acetic acid or other corrosive media, high alloy stainless steel valve or fluoroplastic valve can be selected.

Knowledge of butterfly valve in application
The relationship between the opening of butterfly valve and flow basically changes in linear proportion. If it is used to control the flow, its flow characteristics are also closely related to the flow resistance of the piping. For example, the diameter and form of the valves installed in the two pipelines are the same, and the flow of the valves will be very different if the pipeline loss coefficient is different.
