For steam service
Armstrong’s OB-2000PT is a high-performance
externally piloted pressure/temperature combination regulator for
large-capacity applications such as heat exchangers, steam coils, steam
dryers, plating tanks and parts washers. It should be used in
applications where maximum pressure should be limited and the
temperature of the heated medium is controlled using a single-seated
main valve. Capillary units mount in any position and can be easily
disconnected and interchanged, offering easy installation and maximum
application flexibility. The OB-2000PT is available in sizes 1/2"
through 4" (15–100 mm), with three pressure spring ranges, six
temperature ranges and three capillary lengths.
