First, during storage, the butterfly valve needs to be regularly cleaned of dust or impurities, and placed in a dry and ventilated place. It is better to avoid contact with acid-base accumulations or water sources, as well as wear between valve parts; Second, in the installation process, the first thing is to clean up, the second is to ensure that the installation direction is consistent with the flow direction of the media, and the last is to ensure that the parts are installed tightly and in place; Third, in the process of use, because butterfly valves made of different materials will have different regular maintenance arrangements, remember to apply anti rust oil to ensure the protection of welding joints and timely repair the sealing surface.

Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. The pneumatic butterfly valve uses a round butterfly plate rolling with the valve to open and close, so as to complete the opening action. The pneumatic valve is mainly used as a block valve. It can also be planned to have the function of conditioning or section valve and conditioning. At present, butterfly valves are increasingly used in low-pressure large and medium-sized pipelines.
