This is because we often hear that many people are around us, telling us that life is precious, so as long as we consider this point, we must pay attention to safety issues, so there are many people who feel that they really need to see this in the production line, then we must carry out some serious control, Many people will think whether they should consider it. Of course, if we have this idea, it is a very necessary thing. Maybe some other people do not have this idea. They think they have nothing but to earn more money anyway, It also means that we must ensure our own life safety and the safety of the production line, so the pneumatic ball valve becomes very critical.

Butterfly valve has two sealing types: elastic seal and metal seal. For elastic sealing valve, the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate. Metal sealed valves generally have longer service life than elastic sealed valves, but it is difficult to achieve complete sealing. The metal seal can adapt to higher working temperature, while the elastic seal has the defect of temperature limitation. If the butterfly valve is required to be used as flow control, the main thing is to correctly select the size and type of the valve. The structure principle of butterfly valve is particularly suitable for making large diameter valves.
