About Ball Valves:

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