Disposable valves are e.g. used in connection with branches and terminations where pipelines will not be extended until later.
The valve is temporarily covered with a foamed end fitting.
When the pipeline is extended and the valve is opened the spindle is fully welded.
Please have the internal space requirements in mind, when choosing the dimension of the temporary end fitting and the later permanent casing joint. This depends on whether the valve has a reduced or a full passage.
For further details, see the product data sheet of the valve supplier.
