Abstract
A valve for a branching and/or connecting location of a piggable line for coating material such as paint includes a valve housing for a first throughgoing line, to which at least one second line is selectively connectable, as well as a valve closure body that is spring loaded by a valve spring and that is movable against the force of the valve spring. The valve housing and the valve closure body respectively have flushly aligned bores that have the same contour and the same diameter as each other, and that are directly adjoining each other in the closed position. This diameter is equal to the clear inner diameter of the piggable line. For opening and closing the second line, the valve closure body is movable in the valve housing in the axial direction of the bore thereof.
