With the incorporation of slam-shut valves and on-board monitors, our Pietro Fiorentini regulators provide safeguards against these potential hazards and meet regulatory requirements.
The newest NFPA standards outline when over pressure protection must be provided:
When the supply pressure exceeds the maximum operating pressure of any downstream component.
When the failure of a single upstream line regulator or service pressure regulator leads to a supply pressure surpassing the maximum operating pressure of any downstream component.
