Ball valve is a form of quarter-turn valve that matches TOP electric actuators and uses hollow, perforated and pivotable balls to control the flow through it. When the hole of the ball is in line with the flow, the valve opens; when the handle of the valve rotates it 90 degrees, the valve closes. The handle is in line with the flow when it is open, and perpendicular to the flow when it is closed to facilitate visual confirmation of the valve status.
