ABSTRACT:
A valve member fitting utilizing a frangible closure wherein the fitting may be used with precharged conduits such as employed in the refrigeration arts. Additionally, the invention relates to fitting for precharged conduit systems utilizing frangible closure elements. A frangible valve element seals the passage of a valve, or conduit, and includes an axial portion engagable by a radially movable actuator capable of engaging the valve element and shearing a frangible web to completely remove the valve element from the flow passage, and a valve element receptacle retains the severed valve element. The valve is characterized by its economy of manufacture and absence of flow restriction.
