US/S-X & US/S-XR SURFACE SENSING TEMPERATURE CONTROL VALVE Maintains optimal process temperature Prevents process overheating Self-operating, no power or signal required Discharges minimum amount of media for temperature control • Quick and easy installation • Long service life DESIGN FEATURES • • • • • • All stainless steel construction Exclusive Thermoloid® thermal actuator Narrow temperature band Compact low mass - fast response Ram-type plug for reliable shut off Unaffected by pressure variations APPLICATIONS These compact self contained 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, etc. In general they can be used whenever accurate but low cost control is required. The reverse acting model, US/S-XR can be used to control cooling media to economically remove heat from equipment or a process SAMPLE APPLICATIONS INLET MEDIA INLET TRACING LINE HEAT TRANSFER COMPOUND OPERATION The US/S-X and US/S-XR valves’ Thermoloid® thermal actuator element may be placed in contact with the process line or pipe with the optional band-o-let, or in the line with the integral 3/4” NPT bushing. This allows the temperature element to be in contact with the process to control the valve and regulate the inflow of heating media (or cooling media with the US/S-XR). Input temperatures or steam supply can vary widely, but the control temperature is maintained within desired limits. HEAT EXCHANGER MEDIA INLET TRAP US/S-XR PROCESS
