A Restrictive Flow Orifice (RFO) is a type of orifice plate. They are used to limit the potential danger, damage, or wastage of an uncontrolled flow from, for example, a compressed gas cylinder They are generally not limiting the flow during normal operation but if a fault or failure occurs causing uncontrolled flow the orifice will present a restriction, limiting the flow. It may be used to limit the accidental release of a hazardous gas (flammable, toxic, etc.) resulting from regulator o… WebFlow Limiting Orifices create quantitative airflow through a MF-Millipore filter for airborne contamination analysis.
