About the FDO16 series back pressure regulator

Cv: 1·E-2 to 19  |  Max. Temperature: 150°C  |  Max. Pressure: 10 barg (150 PSI)


The FDO16 is a 2″ high-flow sanitary back pressure regulator. 2” sanitary Tri-Clamp connections are standard on these devices. Tube stubs are an option for this regulator as well. The 2″ size is conveniently sized for Clean-in-Place systems or as a means of controlling large streams in BioPharma or hygienic industrial blending streams.

The FDO16 units is a high-flow back pressure regulator that is often used in production plants. The unit has a Cv rang from 1·E-2 up to 19. This means that it has a turndown ratio of 1:12000. The units are typically used in a range from 400 ml/min up to 850 l/min water. Lower flows are easy to achieve by creating a closed loop control. This rangeability is often ideal for Steam In Place (SIP) and Clean In Place (CIP) procedures. The low flow is used during the a standard process run and the large capacity allows purging with high flows. The diaphragm is the only moving part making the regulator trespond incredibly quick to any change in process conditions. A small movement of the diaphragm enables the unit to release a very large amount of flow.

This model is standard available in SS316 or Hastelloy 276. The diaphragm is made out of USP Class VI PTFE. O-rings, like Kalrez 6230 or PEF encapsulated O-rings are used and FDA approved.
