Features:

1.Small fluid resistance.Ball valve has the smallest fluid resistance among all of the valves,even if the reduced ball valve.
2.Easier and convenient to be open and closed.Ball valve will be full open and full closed only if we turn the stem into 90°.
3.Good sealing.The o-ring of the ball valve’s seat is usually make up with PTFE.And the sealing force increases with the pressure increase.
4.Stem has good sealing.The stem only rotates around the stem when the ball valve is open or close,so the packing seal of the stem is hard to be destroyed.
5.Ball valve only turn 90°when it’s open or closed,so it’s easy to be achieved automation control and remote control.
6.Ball valves are usually glossy and smooth.It’s hard to deposit medium .

Application:

1.Medium’s piping such as SO2,vapour,air,coal gas,ammonia,CO2,oil,water,brine,lye,seawater,nitricacid,hydrochloric acid,sulphuric acid,phosphoric acid etc.

2.In industry of food,chemical industry, medicine,petrifaction and smelt etc.
