ABSTRACT:
An add-on valve assembly for dual-component cartridge has a valve member and a retainer nut which secures the valve member to a dual-component material cartridge. The valve member includes a body having a forwardly extending threaded nozzle and rearwardly extending top and bottom tubes. First and second passageways are formed in the top and bottom tubes, respectively, and extend through the body and nozzle. A valve stem extends generally vertically within the body and is rotatably mounted therein. The valve stem is formed with top and bottom holes which align with the first and second passageways, respectively, when the add-on valve assembly is rotated to an open position and which extend perpendicular to the first and second passageways, respectively, when the add-on valve assembly is rotated to a closed position. The tubes are adapted to extend within respective passageways of the material cartridge and communicate with a pair of chambers formed within the material cartridge. A handle is used to rotate the valve stem between the open position which allows the materials contained within the material cartridge to flow through the first and second passageways and a closed position which prevents the material from flowing through the first and second passageways. A motionless mixing tube may threadably engage the nozzle of the valve member to mix the materials before the materials are dispensed from the material cartridge.
