First, wear-resistant; Because the valve core of the hard seal ball valve is alloy steel spray welding, and the seal ring is alloy steel overlay welding, the hard seal ball valve will not cause much wear and tear when switching. (Its hardness coefficient is 65-70).

Second, the sealing performance is good; because the hard seal ball valve is sealed by manual grinding, until the valve core and the sealing ring completely match can not be used. So his sealing performance is reliable.

Third, the switch is light; because the bottom of the seal ring of the hard seal ball valve uses a spring to tightly hold the seal ring and the valve core together, the switch is very light when the external force exceeds the pretension force of the spring.

Fourth, long service life: has been widely used in petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rocket and other departments, as well as people's daily life.
