A ball valve is a valve with a spherical ball with an orfice straight through mounted between teflon seats in either a screwed or flanged body in various materials. When the orfice is in line with both ends of the valve, flow will occur. When the valve is closed the orfice is perpendicular to the ends of the valve. The lever/handle will be in line with the orfice position, an indication of the valve position.
