ABSTRACT:
A method for inserting a valve in a line, including polyethylene, PVC, plastic, and copper line, pipe, and tubing, without, for example, having to first shut down a line containing fluid under pressure, includes the step of providing first and second ball valve subassemblies that are adapted to be assembled over the line to form a ball valve assembly having a ball component within a housing component. The ball defines a bore, includes cutting edges, and is adapted to be rotated ninety degrees within the housing about an axis of ball rotation perpendicular to the central axis of the bore. The method proceeds by assembling the first and second ball valve subassemblies over the line, and rotating the ball relative to the line so that the cutting edges on the ball cut out a section of the line. In one embodiment, the ball is rotated ninety degrees within the housing about the axis of ball rotation so that the cutting edges slice through the line. In another embodiment, the second subassembly is adapted to enable the user to rotate the housing and the ball on the line as the ball is rotated ninety degrees to the closed position in order to thereby facilitate cutting.
