1、Good wear resistance; as a result of the fact that the hard sealing ball valve is alloy steel spray welding, and the sealing ring is alloy steel welding, so hard seal ball valve will not produce too much wear in the switch.
2、Sealing performance is good. Because the hard seal ball valve is used in artificial grinding, it will not be used until the valve core and the sealing ring is fully consistent. So the sealing performance is reliable.
3、Light switch. Due to the sealing ring of the hard sealing ball valve utilizes a spring, which holds the sealing ring and the valve core together tightly, so the switch is very light when the external force exceeds the spring preload.
4、Long service life: it has been widely used in petroleum, chemical, power generation, paper, aviation and other departments, as well as people's daily life.
