About the H3PF back pressure regulators

Cv: 1·E-0.5 to 0.5  |  Max. Temperature: 300°C  |  Max. Pressure: 206 barg (3000 PSI)


These H3PF units are an extension of the High Flow series. It has 28 inlet orifices and 11 larger outlet orifices, therefore it can digest more flow than any other research series back pressure regulator. Furthermore, a thicker body enables the unit to withstand pressure up to 206 bar (3000 PSI).

Check out the explanation of the High-Flow series in this video.


With a maximum capacity up to a Cv of 0,6 close to a 1000 ln/min can be released from your process while maintaining a constant pressure. Its turndown ratio of 1:100.000 helps to keep this constant pressure even if the flow drops to a few mln/min.
