We should also make it clear that the pneumatic ball valve should be properly inspected and maintained when it is used. The main purpose of this is to timely lubricate the areas lacking lubrication and clean the dirty areas. And another aspect is to really ensure that small problems can be found in time to avoid these problems becoming big problems. Taking the actual situation of this aspect into consideration, it is a guarantee that you can solve many small problems reasonably, and finally deal with the situation better.

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
