Description
The Watts 0559104 Temperature Control Valve 3/4″ Union Thread 90°F – 160°F LF1170-UTM2 is a thermostatic valve to regulate water temperature in HVAC systems. It automatically adjusts flow to maintain a set temperature range, typically installed in hydronic heating, radiant heating, or hot water distribution systems. By controlling water temperature, the valve protects downstream equipment, such as boilers and heat exchangers, from overheating and ensures consistent comfort and system efficiency. Its union-thread design allows for straightforward installation or replacement, making it an essential component for precise temperature.
