Product description

Relief valves are designed to open at a preset pressure (or temperature) level and relieve the system when it has exceeded the desired level. The valve's relief of elevated liquid, gas, or steam pressures prevents damage to the system. Series SL100XL extended shank temperature and pressure relief valves are used in water heater and hot water storage tank applications to provide automatic temperature and pressure protection to hot water supply tanks and hot water heaters up to 105,000 BTU/hr.

Interpretation

The analysis of Watts valve products provides useful insights regarding the cradle-to-grave environmental impacts. The LCA results also identify where substantial impacts are occurring to allow further process and materials improvements to be implemented by Watts. The cradle-to-grave impacts for all products are dominated by the B4 replacement phase as ~2.8 declared units are needed to reach the 75 year building lifespan per the PCR requirement. This stage typically accounts for ~70% of the impacts throughout the products' lifecycle. After this the second largest contributor is the A1 Raw Materials Extraction and Processing stage. This stage accounts for ~10-20% of the lifecycle impacts. The A3 Manufacturing stage accounts for 5-10% of the impacts, with the other stages accounting for <1%.

LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
