Features of ball valves

1. Wear-resistant; Since the spool of the hard-sealed ball valve is alloy steel spray welded, The sealing ring is alloy steel surfacing welding, so the hard seal ball valve will not produce much wear and tear when it is opened and closed. (It has a hardness coefficient of 65-70)

2. Good sealing performance; Since the sealing of the hard seal ball valve is manually ground, it can not be used until the valve core is completely consistent with the sealing ring. So his sealing performance is reliable.

3. The switch is light; Since the bottom of the sealing ring of the hard seal ball valve is made of a spring to hold the sealing ring and the valve core tightly, 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, rockets and other departments, as well as in people's daily life.
