About the HTF back pressure regulators
|Cv: 1·E-0.5 to 0.5 | Max. Temperature: 450°C | Max. Pressure: 412 bar (6000 PSI)
The Equilibar® HTF series of 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 0,01. When you compare this to traditional valves, the rangeability of 1:1000 is still huge. In comparison to Equilibar back pressure regulators build for temperature up to 300°C with a rangeability of 1:100.000, we can call the rangeability a compromise.
In order to prevent condensation, customers often use high temperature units. The multi-orifice design can cope with the two-phase flow. However, if you do not want to influence the composition of the exhaust of the reaction, you need higher temperatures. In case you need higher temperatures than 300°C, we can apply Graphite o-rings and Grafoil diaphragms.
