Description
The Watts F121456 Temperature & Pressure Relief Valve LF140X-6 is a safety control system used to manage excess pressure and temperature within HVAC systems, water heaters, and boiler equipment. Installed on storage tanks and heating vessels, it automatically discharges fluid when internal conditions exceed rated limits of 125 PSI and 210F. Its operations within the system assembly support to protect heat exchangers, piping, and connected components from stress during thermal expansion and pressure buildup. The valve is used in HVAC systems where controlled release operations are required for equipment protection during heating operation.
