Temperature control valve TV/US-X

for steamstainless steelheating

The TV/US-X is a steam heat tracing control valve that monitors and controls the flow of heating media such as steam, gar, or liquid in response to process temperature or pipe surface temperature, protecting facility pipes and equipment from freezing. Operation The self-actuating, thermostatic TV/US-X (Tube Fitting/Ultra Surface Sensing) sample cooler control valve operates the same as the US/S-X valve where the sensing end is either immersed in the process fluid or mounted non-invasively via a hose clamp on the outside of the pipeline. The two differences are that the heating media is connected with tube compression fittings instead of pipe fittings and the Cv is around half of the US/S-X valve. When immersed in the process fluid, the thermal actuator in the valve automatically senses when the temperature rises above the valve’s set-point and modulates closed to keep the process fluid heated at a specified temperature within a 10°F differential. For example, a 90°F valve would open at 90°F and close at 100°F, always keeping the process fluid between 90 – 100°F. Typical Applications These self-contained and compact thermostatic sample cooler control valves can maintain very tight temperature control of any number of control loops using steam, liquid phase heat transfer media such as Dowtherm®, hot water, hot oil, glycol, compressed air, etc. Sample heating applications are commonly controlled by the TV/US-X, but they can be used whenever accurate, low cost control is required.
