About the HTF back pressure regulators

Cv: 1·E-0.5 to 0.5  |  Max. Temperature: 450°C  |  Max. Pressure: 412 barg (6000 PSI)


The Equilibar® HTF series is an extension of the HT (high temperature) series. We increased the maximum Cv to 0,5 while the standard high temperature units are limited to 0,07. When you compare this to traditional valves that offer rangeability of 1:50, the rangeability of this HTF-series (1:10.000) is huge. Nevertheless, Equilibar back pressure regulators built for temperatures up to 300°C  feature a rangeability of 1:100.000; the somewhat smaller rangeability of this HTF series thus enables significantly broader flow ranges.

To prevent condensation, customers often use high temperature units. Our unique multi-orifice design can cope with two-phase flow. However, when your process does not allow the regulator to influence the reaction composition, you may need to apply higher temperatures in your regulator. This HTF series meets these requirements.

For temperatures above 300°C, we offer Graphite seals combined with SS316 diaphragms.
