Watts 0556050 Valve
The Watts 0556050 (Series LF4L) is a high-performance 3/4 inch pressure relief valve specifically engineered for tankless water heaters and domestic storage tanks. Featuring a lead-free copper silicon alloy body, this poppet-type valve is designed to mitigate excessive pressure risks in residential and commercial plumbing systems. It arrives factory-set at 150 psi and features a durable stainless steel spring and silicone disc to ensure a tight seal and consistent blow-down performance. As a veteran-grade ASME Section IV rated component, it provides a steam discharge capacity of up to 500,000 BTU/hr, making it a reliable choice for high-demand hot water applications where temperature relief is handled by other system components.
Key Benefits for the Contractor:- Lead-Free Construction: Complies with all safe drinking water acts, utilizing a forged lead-free copper alloy for maximum corrosion resistance.
- Simplified Installation: Features a 3/4" MNPT inlet and a 3/4" FNPT outlet (drain) for direct integration into standard piping layouts.
- Tested Reliability: Equipped with an integrated test lever for manual verification of valve seat functionality during routine maintenance.
- Code Compliance: ANSI Z21.22 approved and CSA listed, ensuring your installations meet strict local and national plumbing codes.
Is this a combination temperature and pressure (T&P) valve? No. The LF4L is a pressure-only relief valve. If your application requires thermal expansion protection, ensure you are using a 100XL series or similar T&P rated valve.
Can I use this on a standard tank-style water heater? Yes, provided that the system pressure requirements do not exceed 150 psi and the heating capacity is within the 500,000 BTU/hr steam rating.
What is the difference between the LF4L and the LF3L? While similar in poppet design, the LF4L is specifically optimized for the high-flow requirements and pressure profiles of modern tankless systems.
