1. A barrel valve assembly comprising:
(a) a barrel valve comprising a cylindrical, hollow body having at least one opposite open end(s) wherein the body is intersected laterally across and through by an off-axis passage; and
(b) a cylindrical liner comprised of a hollow shell configured to receive the body of the barrel valve inside the liner wherein the liner comprises a pair of mutually opposite apertures, which are located near the cross-section of the off-axis passage of the barrel valve;
wherein the barrel valve is situated and rotatable within the liner, both having a coincident axis of symmetry;
wherein when the body of the barrel valve is rotated about its axis of symmetry, such that when the off-axis passage is fully aligned with the mutually opposite apertures of the liner, the valve assembly is in an open orientation; when the off-axis passage is fully misaligned with the mutually opposite apertures, the valve assembly is in a closed orientation; and when the off-axis passage is partially aligned with the mutually opposite apertures of the liner, the valve assembly is in a partially open orientation; and
wherein the liner comprises at least one orifice formed through the liner and the body of the barrel valve comprises at least one rotation limiting channel formed on an outer surface of the body, wherein each of the at least one orifice is capable of being aligned with a respective one of the at least one rotation limiting channel formed on the outer surface of the body when the body is disposed within the liner.
