Three type ball valve
Three type ball valve sealing ring is alloy steel welding, so hard seal ball valve when the switch does not produce too much wear and tear. its hardness coefficient for 65-70.
3.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.
