ABSTRACT:
A line-removable valve structure comprising a pipeline-supporting cage and a cartridge containing the working valve components. The cage comprises a pair of thick steel end plates connected by studs and a balanced array of hydraulic rams. With nuts on the studs loosened, the rams can force the end plates apart for removal of the valve cartridge. Sliding guide means are provided to enable such axial movement of the end plates but to prevent relative radial movement thereof, thus maintaining the integrity of the pipeline.
