Features of pneumatic on the butt butterfly valve:
1. The structure of the pneumatic to the side of the butterfly valve is the three eccentric sealing structure, and there can even achieve zero resistance between the butterfly plate and the valve seat, so that it has the closing sealing performance.
2, the sealing ring made from stainless steel has a metal hard seal and a double advantage of the elastic seal. Whether it is in low temperatures or high temperature environments, it has a good sealing performance, corrosion resistance, and long service life.
3, using a plate-strip-resistant surface of the solder cobalt-based rigid alloy, strong wear resistance, greatly improves the service life.
4, pneumatic pair of crotch butterfly valves have two-way sealing function, and is not limited by the flow of media during installation, and it is not affected by the spatial position, which can be installed in any direction.
5. The drive can be installed multi-station (rotated 90 ° or 180 °) for easy use.
It is because of these features, pneumatic to the bristles are mainly used in the pipelines of metallurgy, electric power, petroleum, chemical, air, gas, combustible gases, and water supply and drainage, which is a good in regulating flow and truncation fluid. Device.
