The self discharging valve seat and valve seat can ensure their tightness through reasonable design, and each side bears the full pressure difference of the pipeline. Since the working principle and stress state of the two valve seats are different, they can be selected according to different needs. It is recommended to adopt the self discharging valve seat structure for the pipeline conveying oil products.

Plastic coated pneumatic butterfly valve to your satisfaction
We can see all kinds of wires and cables in many places. These things are wrapped by a pipe called plastic coated pneumatic butterfly valve. From this we can see that plastic coated pneumatic butterfly valve is a kind of wire maintenance jacket, which can maintain some fine instruments well. Normally, if the wires beside the road are not covered with a layer of plastic coated pneumatic butterfly valve, it is easy to fail to transmit power when the wires are exposed to the wind, rain and sun for a long time. If the wires are wrapped with maintenance pipes, they can withstand the test of the weather for a long time. At present, not only the electric power industry will use this kind of hose, but also the chemical and metallurgical industries often need plastic coated pneumatic butterfly valves. We all know that the biggest defect of the line is that it will appear aging after a long time. But once the hose is used to wrap it outside, it can easily avoid the damage of ultraviolet rays to the line, and at the same time, it can be more anti-aging. The tight structure provides a guarantee for equipment in every industry.
