    About the High Temperature series back pressure regulators

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


    Customers use the units from the High Temperature series often in certain applications. Within these applications, the condensation of the media coming from a reactor should not go back into the liquid phase. Although the multi-orifice design can cope with the two phase flow, it should not influence the composition of the exhaust from the reaction.

    Customers can use a standard Equilibar® back pressure regulator from up to 300°C. The back pressure regulators can use Graphite o-rings and Grafoil diaphragms to withstand higher temperatures. In comparison with traditional valves, the rangeability of 1:1000 is still very large. Since the Equilibar back pressure regulators are built for temperatures up to 300°C, the rangeability is somewhat compromised.

    The use of Graphite o-rings requires a bigger torque to get good sealing. Therefore we reduce this problem in the UHT (Ultra High Temperature) series. We keep the diaphragm in place. Furthermore, we use Silver coated Inconel o-rings in the unit to create a seal to the environment. Our blog about this topic is especially relevant, please find the link below.
    Our high temperature back pressure regulators are now resistant to 700°C!”
