<p>The present invention comprises an improved method and apparatus, associated with a self-piercing valve assembly (10) for mounting the self-piercing valve on a pipe (11) and for constraining movement of the valve on the pipe. In accordance with a preferred embodiment of the present invention, a self-piercing valve assembly (10) comprises a clamping assembly (13) and a crimping member (58) associated with the clamping assembly, which crimping member 'automatically' crimps a pipe and forms a recess therein when the self-piercing valve clamping assembly is tightened about the pipe, and simultaneously effects a crimping member/recess interface (59) (much like a key-and-keyway interface) which inhibits relative angular rotation between the pipe and valve. The crimping member is, preferably, a rigid, projection or tab.</p> |
