The Ball Valve Features
Ball valve such as the Cast Steel Ball Valve features:
First, wear resistance; because the valve core of the hard seal ball valve is alloy steel spray welding,Three-piece ball valve
Three-piece ball valve
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):
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
