High pressure ball valve

Firstly, it has good wear resistance, as its valve core seal is welded to alloy steel, and its sealing ring is also welded to alloy steel.

Secondly, the sealing performance is good, and the sealing reliability of the ball valve is extremely high because its sealing is manually run in, and only when the valve core and sealing ring completely overlap can it be achieved. Thirdly, the switch of the ball valve is light, and there is a spring at the bottom of the sealing ring between the valve core and the sealing ring.

Fourthly, the service life of ball valves is relatively long, and they are mostly used in China's petroleum industry, chemical product manufacturing industry, power plants, paper mills, and other places.
