What is the difference between the manufacturer's price of electric flange type ventilation butterfly valve and electric butterfly valve? The reason why the new model of pneumatic ball valve is expensive is that the design concept and manufacturing process of the new model of pneumatic ball valve are relatively new, which can adapt to most of the current systems, make the work more efficient and work more outstanding.
、 Generally, the base of the valve is an inclined sealing surface, so all materials will accumulate on the sealing surface, which is difficult to discharge quickly in a short time. The above situation will not occur for pneumatic butterfly valves. Even if there is very little material on the sealing surface, the residual materials can be completely scraped off when the valve automatically closes.
