First of all, check the quality before installing the electric butterfly valve. Many novices are very anxious when installing, thinking that the whole work will be completed after installing. There are unqualified products among products of different brands. Once we choose this product when installing it, even if you install it correctly, you can't use it. Learn to check the product and install it only when there is no problem. This is the most basic thing. Don't wait for your installation to complete before you find the problem. It will be even more troublesome at this time.

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
