Can regulator protection be integral with the regulator according to NFPA regulations?

In accordance with NFPA regulations, it is permitted for regulator protection to be integral with the regulator. This means that the design of the regulator can include built-in protective features that shield it from impacts, environmental factors, or other potential hazards. The integration ensures that the regulator is not only functional in controlling gas flow but also safeguarded within its own construction, which can contribute to both safety and efficiency in gas delivery systems.

The allowance for this integrated design can streamline installations and reduce the need for additional protective measures, as long as the combined unit meets the necessary safety and performance standards outlined in the regulations. This consideration is particularly relevant for applications where space or simplicity in installation may be advantageous.

Other options suggest additional restrictions or circumstances under which the regulator protection could be designed, but the NFPA guidelines clearly allow for this integration as a viable and acceptable practice.
