A flow device (1600;1700;1800;1900;2000) for controlling flow during an agricultural operation, comprising: an inlet ; an outlet passage (1630; 1730;1830;1930;2030); an offset ball valve (1650;1750;1850;1950;2050); a first passage (1610;1710) from the inlet to the offset ball valve; a second passage (1620;1720;1820;1920;2020) from the inlet to the offset ball valve; the offset ball valve having first and second openings (1751,1753; 1851,1853;1951,1953;2051,2053) that rotate in position to control flow of a liquid through the offset ball valve (1650;1750;1850;1950;2050) from the first passage and/or the second passage to the outlet passage (1630; 1730;1830;1930;2030) dependent on the position of the offset ball valve; the first passage (1610;1710) to provide a first flow path (1614;1714,1715) from the inlet to the first opening of the offset ball valve (1650;1750) to the outlet passage (1630;1730) when the offset ball valve is positioned to place the first opening in fluid communication with the first passage; and the second passage (1620;1720;1820;1920;2020) to provide a second flow path (1622;1722;1822;1922;2022) from the inlet to the first opening of the offset ball valve (1650; 1750) to the outlet passage (1630; 1730;1830;1930;2030) when the offset ball valve is positioned to place the first opening in fluid communication with the second passage; characterized in that the first and second openings (1751,1753;1851,1853;1951,1953;2051,2053) of the offset ball valve (1650;1750;1850;1950;2050) each comprise a cylindrical shaped bore that are positioned in fluid communication with each other with a configurable angle of 10 to 40 degrees. an inlet ; an outlet passage (1630; 1730;1830;1930;2030); an offset ball valve (1650;1750;1850;1950;2050); a first passage (1610;1710) from the inlet to the offset ball valve; a second passage (1620;1720;1820;1920;2020) from the inlet to the offset ball valve; the offset ball valve having first and second openings (1751,1753; 1851,1853;1951,1953;2051,2053) that rotate in position to control flow of a liquid through the offset ball valve (1650;1750;1850;1950;2050) from the first passage and/or the second passage to the outlet passage (1630; 1730;1830;1930;2030) dependent on the position of the offset ball valve; the first passage (1610;1710) to provide a first flow path (1614;1714,1715) from the inlet to the first opening of the offset ball valve (1650;1750) to the outlet passage (1630;1730) when the offset ball valve is positioned to place the first opening in fluid communication with the first passage; and the second passage (1620;1720;1820;1920;2020) to provide a second flow path (1622;1722;1822;1922;2022) from the inlet to the first opening of the offset ball valve (1650; 1750) to the outlet passage (1630; 1730;1830;1930;2030) when the offset ball valve is positioned to place the first opening in fluid communication with the second passage; characterized in that the first and second openings (1751,1753;1851,1853;1951,1953;2051,2053) of the offset ball valve (1650;1750;1850;1950;2050) each comprise a cylindrical shaped bore that are positioned in fluid communication with each other with a configurable angle of 10 to 40 degrees. <EOS>
