The Characteristics Of The Ball Valve

Wear resistance; As a result of the hard seal ball valve valve core is alloy spray welding, sealing ring is alloy steel welding, so hard seal ball valve when the switch is no wear and tear. (its hardness coefficient for 65-70) :

Good sealing performance; Because of the hard sealing ball valve's sealing is using artificial grinding, until the valve core and seal perfectly before using. So he sealed performance is reliable.

Light switch; Due to adopting the spring hard seal ball valve at the bottom of the sealing ring seal and valve core embrace together tightly, so in the outside powers over spring pre-tightening force when the switch is very light.
