1. Wear resistance; since 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 does not cause too much wear when switching. (It has a hardness coefficient of 65-70):
2. Good sealing performance; since the seal of the hard seal ball valve is artificially ground, it can be used until the valve core and the seal ring are completely matched. Therefore, his sealing performance is reliable.
3. The switch is light; since the bottom of the seal ring of the hard seal ball valve uses a spring to hold the seal ring tightly with the valve core, 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, power generation, papermaking, atomic energy, aviation, rocket and other departments, as well as people's daily life.
The pneumatic ball valve is simple and compact in structure, reliable in sealing and convenient in maintenance. The sealing surface and the spherical surface are often closed, which is not easily eroded by the medium, easy to operate and maintain. It is suitable for general working medium such as water, solvent, acid and natural gas, mainly used for cutting off. Or turn on the medium in the pipeline, or use it for fluid regulation and control.
