Product Brochure



The FPD201 is a single chamber orifice fitting. It enables the orifice plate to be inspected and / or replaced without removing the fitting itself from the pipeline. However, the process must be shut down and depressurized before the plate can be removed.

Here are the key features of the FPD201:

  • Economical orifice installation
