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.
