High Temperature Applications
Precision back pressure regulators with SS316 diaphragms
Equilibar's new Instrument Series back pressure regulators extend our unmatched precision to higher temperature applications, such as those in the petrochemical and catalyst research laboratories.
The EB1HP1 regulator (see brochure) can be fitted with SS316 diaphragms, which extend the pressure range up to 5000 psig, while also pushing the operating temperature range up to that of Kalrez® o-rings (300°C, 527°F).
While Equilibar's PTFE/Glass composite diaphragms can be up to 232°C (450°F) at low pressures, the mechanical stress derating for PTFE at elevated temperatures make the SS316 diaphragm a more practical choice in most high temperature applications. Diaphragm of Hastelloy C are also available for some applications.
SS316 diaphragms can also be fitted onto larger regulators where required on a custom design basis. Contact our engineers for more information.
