The price of pneumatic ball valves is different, mainly because there are certain differences in models. We can really understand these practical aspects, and there will be a day for the whole thing, so it will have more impact on you. So I hope everyone can understand it clearly. The specific functions of different models will be different. We can pay more attention to these differences before making choices. It is best to really understand your needs for the model, and then make a decision on this basis.

Structural characteristics of electric butterfly valve
1. Under high temperature and high pressure conditions, it still has a stable sealing function. Its special sealing system can ensure that all temperature scales from ultra-low temperature to ultra-high temperature have a high sealing function
2. The 3D preferential sealing system and the optimized design make the opening resistance of the valve small. The sealing surface of the butterfly plate is a cone that is always convex upward. When opening, all points on the circumference of the butterfly plate are closed together and separated from the sealing ring, and solids are not easy to accumulate on the sealing surface. The sealing process of the valve is closed through the elastic pressure of the sealing ring
3. There is no phase jam between butterfly plate and sealing ring
4. The sealing function of the valve is not affected by temperature change
5. The shaft diameter seal of valve rod adopts graphite constrained forming seal ring. In conclusion, zero leakage is guaranteed. The metal seal is zero leakage before, during and after the fire, so it is intrinsically fire safe
