Abstract
A pipeline control unit that joins pipeline conduits and has a housing with an interior compartment for receiving a gate. A valve servicing assembly or pressure plates can be installed onto the housing to form a fluid tight structure to allow removal and replacement of a retained gate without depressurizing a pipeline system. Strongbacks attached to the housing can compress lateral walls of the housing to secure a gate in the interior compartment, and removal of such compression allows removal of the gate while the pipeline is pressurized.
