Long life diamond orifices!

What’s in a name? A lot in this case, they are called Long Life Orifices for a good reason. These orifices have inserts made of diamond, the hardest and most wear resistant material available. The longer lifetime of a diamond orifice not only results in a reduction of the number of orifices used. It also means the orifice keeps its accuracy and precision for a longer period. This allows for a better performance and a significantly reduced system down-time for orifice replacement and system calibration. All together the use of Long Life Orifices will make the entire process more cost-effective.

Dutch Diamond Group offers a wide assortment of diamond orifices for just about any job. All orifices are built to OEM specifications and in partnership with system manufacturers. For greater productivity and lower overall costs, performance can be tailored to the exact job requirements.
