Is the pneumatic square ventilation butterfly valve electric at a low price sale? Secondly, because of the internal leakage caused by the product quality, we all know this problem very well, even if we don't use small editors. Because this is a quality problem, using other methods does not work at all. However, it is also necessary to introduce to you that in production, if the valve material, processing technology and assembly process are not strictly controlled, it will lead to unqualified grinding of the sealing surface, sand holes and other defects. At the same time, if these defects have not been completely eliminated, it will lead to internal leakage of the pneumatic butterfly valve, so the sealing surface needs to be processed again.
、 Second, as the leakage stoppers of electric butterfly valves, they should have a sense of responsibility, because they can operate the device skillfully with rich experience, so the leakage stoppers should not be too many, and 1-2 people should be skilled.
