What are the unique characteristics of ball valves?

1. Wear resistance: Since the spool of the hard-sealed ball valve is spray-welded with alloy steel, and the sealing ring is surfacing with alloy steel, the hard-sealed ball valve will not cause too much wear when switching. (It has a hardness factor of 65-70)
2. Good sealing performance; because the seal of the hard-sealed ball valve is manually ground, it cannot be used until the valve core and the sealing ring are completely matched. So his sealing performance is reliable.
3. The switch is light; since the bottom of the sealing ring of the hard-sealed ball valve uses a spring to tightly hug the sealing ring and the valve core, the switch is very light when the external force exceeds the pre-tightening force 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 in people's daily life.
