The Q41F ball valve has the same 90 degree rotation action, but the difference is that the plug body is a sphere with a circular through-hole or channel passing through its axis. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. They can be tightly closed with only a 90 degree rotation and a small rotational torque.
