Last summer, there was a quality problem with the pipeline ball valve in the factory. I contacted several valve manufacturers. Two manufacturers were selected.

Some ball valves of the same model are heavier, some are lighter, and the light ones are of course cheaper. In order to reduce the cost, some factories have reduced the thickness of the valve body and the weight of the valve is light. The safety factor of this valve used in pipeline will be very small, and it feels unreliable. Although I'm not sure, there is no uniform weight in the market, and there will be valve blanks when manufacturers produce valves. And this blank will have many choices in the production process. Hongye valve adopts silica sol casting in the production process. Because the silica sol casting process is fine, the valve produced is much heavier than the general valve, and Hongye itself is an integrated process of casting machine processing, and the standard of the valve is quite strict. After all, this is a manufacturer with a long history, and its qualification and reputation are guaranteed.
