First, wear resistance; because the valve core of the hard seal ball valve is alloy steel spray welding, the seal ring is alloy steel surfacing, so the hard seal ball valve will not produce too much wear when switching. (It has a hardness coefficient of 65-70):
Second, the sealing performance is good; because the seal of the hard-sealed ball valve is artificially ground, it can be used until the valve core and the sealing ring are completely matched. Therefore, his sealing performance is reliable.
Third, the switch is light; because the bottom of the sealing ring of the hard-sealed ball valve uses a spring to tightly hold the sealing ring and the valve core, the switch is very light when the external force exceeds the pre-tightening force of the spring.
Fourth, long service life: has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rocket and other departments, as well as people's daily lives.
The pneumatic ball valve is simple and compact in structure, reliable in sealing, convenient in maintenance, and the sealing surface and the spherical surface are often closed, which is not easily eroded by the medium, easy to operate and maintain, and is suitable for general working medium such as water, solvent, acid and natural gas, and is mainly used for cutting off. Or turn on the medium in the pipeline, or use it for fluid regulation and control.
