Sterling-Sterlco D-152-G 1 Inch Da Temperature Cntrl Valve 175-215F

The Sterling-Sterlco D-152-G is a one-inch-diameter automatic temperature control valve that is used in many HVAC systems. It controls the flow of hot or cold water by responding to temperature variations within a specific range, usually between 175 and 215 degrees Fahrenheit. The valve automatically changes to either raise or decrease the flow of cold water or hot water when the temperature rises, and vice versa. This aids in preserving the proper temperature over time in heating and cooling systems, such as geothermal, chilled water, and hydronic systems. The D-152-G improves comfort, increases system efficiency, and protects equipment from overheating or overcooling by maintaining stable temperatures.
