Features Of Ball Valves
Nov 06, 2018

One; wear-resistant; because the valve core of hard seal ball valve is alloy steel spray welding, sealing ring is alloy steel surfacing, so hard seal ball valve in the switch will not produce too much wear.

(It has a hardness coefficient of 65-70): 

Two; good sealing performance; Because the seal of the hard sealed ball valve is artificially ground, until the valve core is fully in line with the seal ring to be used.

So his sealing performance is reliable.

three; light switch; because the bottom of the sealing ring of the hard sealed ball valve uses a spring to hold the sealing ring tightly with the valve core, the switch is very light when the external force exceeds the preload of the spring. Four; Long service life: has been widely used in petroleum, chemical, power generation, paper, Atomic Energy, aviation, rockets and other departments, as well as people's daily life.
