Product Description
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
Operation
The US/S-X and US/S-XR valve’s Thermoloid® sensor/controller element may be placed against the process line or pipe with the optional weld-o-let or band-o-let, or in the line with the integral 3/4 NPT-M bushing. This allows the temperature element to be in contact with the process to control the valve section 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.
Benefits
Prevents process overheating
Discharges minimum amount of media for temperature control
Maintains optimal process temperature
Quick and easy installation
Long service life
Design Features
All stainless steel construction
Exclusive Thermoloid® sensor/controller
Narrow temperature band
Compact low mass – fast response
Ram-type plug for reliable shut off
Unaffected by pressure variations
