Product description
Hydronic components are needed for creating safe and high performing hydronic and steam heating solutions. They are easy to Install, service, clean, and keep heating systems in compliance with necessary plumbing code and standards. This 1/2 inch high capacity feed water pressure regulator is for use in commercial and residential hydronic heating systems to fill the boiler and piping system with water, and to maintain water pressure in the system at all times. It also provides make-up water to the system in the event of system leaks. It consists of a bronze body with union solder inlet and NPT threaded outlet connections, a tight seating check valve, purge lever for manual purging, and a stainless steel strainer. It has high capacity performance and a simplified servicing design. It is suitable for use in the boiler feed lines of hydronic heating systems.
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.
