Ball valve features
1. Wear resistance; because the valve core of the hard-sealed ball valve is spray-welded with alloy steel, and the sealing ring is made of alloy steel surfacing, so the hard-sealed ball valve will not produce too much wear when it is switched on and off. (Its hardness factor is 65-70).
Second, the sealing performance is good; because the sealing of the hard-sealed ball valve is artificially ground, it cannot be used until the valve core and the sealing ring are completely matched. So his sealing performance is reliable.
Third, the switch is light; because the bottom of the sealing ring of the hard-sealed ball valve adopts a spring to hold the sealing ring and the valve core tightly together, the switch is very light when the external force exceeds the preload of the spring.
4. Long service life: It 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.
