The OB-2000 Series is a high-performance externally piloted temperature regulator for large-capacity applications such as heat exchangers, steam coils, steam dryers, plating tanks and parts washers. Self-actuated and requiring no external energy source, the OB-2000 Series comes with a main valve, pilot valve and tubing kit. Capillary units mount in any position and can be easily disconnected and interchanged, offering easy installation and maximum application flexibility. The OB-2000 Series is available in sizes .5″ through 4″ (15–100 mm), with six temperature ranges and three capillary lengths.
