This dual packing chamber is for use within a valve for existing pipelines. The secondary packing chamber can be easily incorporated into existing valves already in use. In the preferred embodiment, the secondary packing chamber is seated between the body of a valve and the yoke tube. The invention creates a primary packing chamber and a secondary packing chamber that acts as a stopper should the first packing chamber fail to ensure fluid is not accidently released to the environment. |
