More Information about Precision Orifices
Ruby and sapphire precision orifices are used in orifice nozzles and restrictors. Precision orifices are used in applications that require precision flow rates. The most critical factor in obtaining a precise rate of flow and coefficient of discharge (CD) is maintaining a precision orifice. The inside diameter, the roundness, the length of the orifice throat as well as the condition of the orifice edges are all factors that affect the flow through the orifice. High precision orifice tolerances are maintained through the use of laser drilling and wire lapping. Ruby and sapphire are almost as hard as diamond, have five-times the abrasion resistance of carbide, and are chemically inert. Applications that use precision orifices include; O2 analyzers, ink jet printing, high pressure jetting, micro metering, leak detection and chemical spray.
