Imperial Flange and Fitting's Multistage Orifice Assemblies consist of several orifice plates installed in the same pipe. This allows the pressure to gradually be reduced to the desired pressure. Compared to a single orifice, a multistage assembly reduces the pressure in smaller increments which reduces cavitation and noise. A typical application would be to reduce the pressure from 2500 psi down to atmospheric pressure. The assembly could consist of five stages (orifices) each causing a 500 psi pressure drop. Imperial Flange will manufacture custom assemblies to meet your needs.

The images below show a multistage orifice assembly at various stages of manufacture.
