Sapphire Orifice Jewels are a development of the vee jewel and are sometimes called drilled vees. Sapphire is an excellent orifice material because of its resistance to wear, heat and corrosion, as well as its low friction. The hole diameter for control purposes is usually specified to be held within 0.0002”. Sapphire orifices can be used for UHP water jet applications (up to 40,000-50,000 PSI), oil atomizing and the handling of air, hot gases and practically all liquids and acids.

Typical Applications: Control Units (gas, liquid), Flow-meters, Ultra-High Pressure Waterjet Orfices, Ink Jet Printing.
