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[1][2] 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 or other component failure, restricting flow in a system in order to assure adequate pressure relief valve sizing and system over pressure protection, or restricting flow from bulk sources such as a water main.[3]
