    Small diameter PVC compact ball valve, generally with floating PVC compact ball valve, large diameter PVC compact ball valve, because the need for opening and closing torque is relatively large, often choose fixed PVC compact ball valve, can reduce the torque required when opening and closing, improve the reliability of the work. V-type PVC compact ball valve and eccentric half PVC compact ball valve, can be used to adjust the flow, three-way PVC compact ball valve and four-way PVC compact ball valve are used to reverse the fluid.


    PVC compact ball valves are commonly used in carbon steel, 304 stainless steel, 316 stainless steel, for highly corrosive medium, the valve body and ball lined with ptfe. PVC compact ball valve drive mode is mainly electric, pneumatic, worm gear transmission, small caliber manual PVC compact ball valve, are generally used to open and close the handle.
