ABSTRACT:
A valve for conduit systems, such as a base valve for precharged refrigeration circuits, wherein the valve element is initially closed, and is opened by the application of heat to the valve body exterior. The valve element is maintained in a closed or sealed position by a low temperature fusible material, such as solder, and the application of exterior heat melts the fusible material to release the valve element and open the valve to unrestricted flow therethrough. The valve structure includes means for preventing restriction by the released valve element.
