1. Wear resistance: because the valve core of hard seal ball valve is spray welded with alloy steel and the sealing ring is overlaid with alloy steel, the hard seal ball valve will not have too much wear when opening and closing.
2. Good sealing performance; as the hard sealing ball valve is sealed by manual grinding, it can not be used until the valve core and sealing ring are completely consistent. So his sealing performance is reliable.
3. Light switch: since the bottom of the seal ring of the hard seal ball valve is tightly held together with the valve core by the spring, the switch is very light when the external force exceeds the preload of the spring.
