A ball valve is a valve that opens by turning a handle/gear attached to a ball inside the valve. The ball has a hole or port through the middle, so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The handle’s position indicates the valve's position.
