I. Wear-resisting; because the spool of the hard sealing ball valve is the alloy steel spray welding, the sealing ring is the alloy steel surfacing, so the hard sealing ball valve does not produce too much wear when switching. (Its hardness coefficient is 65-70):
II.The sealing performance is good, because the seal of the hard sealing ball valve is used artificially grinding, until the valve core is fully coincident with the sealing ring. So his sealing performance is reliable.
III. Switch light; Because the sealing ring of the hard sealing ball valve adopts the spring to make the sealing ring and the valve core tightly hug, so the switch is very light when the outside force exceeds the preload of spring.
IV. Long service life: has been widely used in petroleum, chemical, power generation, papermaking, Atomic Energy, aviation, rockets and other departments, as well as people's daily life.
Pneumatic ball valves are compact and reliable, simple structure, convenient maintenance, sealing surface and spherical often in closed state, not easy to be dielectric erosion, easy to operate and repair, suitable for water, solvent, acid and natural gas, such as ordinary working medium, mainly used to truncate or connect the media in the pipeline, can also be used for fluid regulation and control.
