Watts 0121515 Valve
The Watts 0121515 (Model LF174A-60) is a heavy-duty, lead-free boiler pressure relief valve engineered specifically for high-capacity overpressure protection in hot water heating and domestic supply systems. Featuring a 1.25" NPT female inlet and outlet, this valve is factory-set to 60 PSI and delivers a significant steam discharge capacity of 2,847,000 BTU/hr. Its ASME Section IV certified design ensures reliable performance in commercial and industrial hydronic applications where maintaining safe operating pressures is critical.
Constructed from a lead-free copper silicon alloy body, the Watts LF174A resists aggressive water conditions. The internal architecture utilizes a non-metallic disc-to-metal seating and a stainless steel spring, focused on preventing the disc from sticking or freezing after long periods of inactivity. The unique raised seat design allows sediment to settle at the bottom of the valve body without fouling the seat, ensuring a tight seal and consistent emergency safety relief. This model also includes a manual test lever for routine system checks and is compatible with SentryPlus Alert technology for flood detection monitoring.
Key Benefits- High BTU Capacity: Rated at 2,847,000 BTU/hr to handle large-scale commercial boiler outputs.
- Lead-Free Construction: Complies with all federal and state regulations for potable and domestic water heating.
- Anti-Foul Design: Raised seat architecture prevents sediment buildup and prevents the valve from sticking.
- Reliable Reseating: Features automatic reseating capabilities and a stainless steel spring for consistent pressure response.
- NPT Threading: Standard 1-1/4 inch female connections facilitate seamless integration into existing hydronic piping.
Is the 1.25" LF174A rated for steam heating?
No, this valve is specifically designed for hot water space heating and domestic supply boilers. It is not intended for steam heating applications.
Can this valve be used as an operating control?
Absolutely not. This is a safety device intended for safety relief only. It should never be used as a primary pressure regulator or operating control.
What is the maximum temperature rating for this model?
The Watts LF174A is designed for systems with temperatures up to 250°F (121°C).
