1. The valve body of the wear-resistant hard-sealed ball valve is sprayed with alloy steel, and the sealing ring is made of alloy steel surfacing, so the hard-sealed ball valve does not wear much during opening and closing.
2. The seal of the hard-sealed ball valve with good sealing performance is artificially ground, so it cannot be used until the valve body and the sealing ring are completely consistent, so its sealing performance is reliable.
3. The bottom of the sealing ring of the hard-sealed ball valve with light switch is tightly hugged by the sealing ring and the spool with a spring, so when the external force exceeds the force of the spring, the switch becomes very light.
4. Long life: widely used in petroleum, chemical industry, power generation, papermaking, nuclear energy, aviation, rocket and other sectors, as well as people's daily life.
The pneumatic ball valve has a simple and compact structure, reliable sealing and convenient maintenance. When the sealing surface and spherical surface are always closed, they are not easily eroded by the medium, and are easy to operate and maintain. They are suitable for general working media such as water, solvent, acid and natural gas, mainly pipes Compared with other types of valves, the road medium air valve has the output torque of the corner stroke, which opens quickly, smoothly, and has high reliability.
