ABSTRACT:
An interchangeable plug valve having a valve body with a first through hole. An outer valve plug having a second through hole. The outer valve plug is rotatably and sealably seated within a first cavity of the valve body. The second through hole of the outer valve plug rotatably aligns with the first through hole of the valve body. The outer valve plug is retained in a seated and sealed position within the valve body. An inner valve plug is non-rotatably and sealably seated within a second cavity of the outer valve plug. A plurality of interchangeable plug valves combine to form a parallel porting valve assembly. The parallel porting valve assembly has a parallel valve body with an inlet channel cavity and an outlet channel cavity. Each interchangeable plug valve has one side of the second through hole of the outer valve plug aligned with the inlet channel cavity and the opposite side of the second through hole of the outer valve plug aligned with the outlet channel cavity of the parallel valve body.
