Pneumatic telescopic flange butterfly valve opening and closing time What is used for the wafer switch

What screws are used for the opening and closing time of pneumatic telescopic flange butterfly valve clamp switch?

Structural characteristics of pneumatic 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

Advantages of pneumatic butterfly valve: its structure is very simple, its volume is very small, and its weight is not too heavy. In low pressure working environment, it can achieve good sealing performance. When we open and close the product, the speed is very fast, and the strength is saved. The fluid resistance is also very small. Our staff can also operate frequently. When we use the pipeline to transport sediment and other similar substances, the liquid stored in the pipeline itself is relatively small, which can greatly reduce the trouble in our work process. If you want to adjust this product, it is also a good choice for our consumers and users. Because of its excellent regulation performance.
