Introduce
A valve that is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control, in which the v-ball core of the hard sealed v-ball valve has a strong shear force between the v-ball core and the metal valve seat of hard-facing carbide, which is especially suitable for medium-containing fiber, small solid particles, etc.
Explain
1. wear resistance; as the valve core of the hard seal ball valve is alloy steel spray welding, The seal ring is alloy steel overlay welding, and the hard seal ball valve will not produce too much wear when opening and closing. (its hardness coefficient is 65-70):
2. Good sealing performance; as the sealing of hard seal ball valve is manual grinding, it can only be used until the valve core and sealing ring are completely consistent. So his sealing performance is reliable.
3. The switch is light; because the bottom of the seal ring of the hard seal ball valve uses the spring to tightly hold the seal ring and the valve core together, 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 lives.
