Watts F276050 Valve
Engineered for high-capacity overpressure protection, the Watts F276050 (Series 174A) is a heavy-duty ASME Section IV boiler relief valve designed specifically for hot water heating supply boilers. Featuring a robust bronze body and 1-1/4 inch female NPT connections, this valve is factory-set at 125 PSI with an impressive discharge capacity of 5,370,000 BTU/hr. Unlike standard hardware, this unit utilizes a non-metallic disc-to-metal seating and a stainless steel spring to prevent sticking or freezing, even in systems where corrosive water conditions or sediment buildup are a concern. The integrated SentryPlus Alert flood sensor allows for remote monitoring of discharge events when paired with a compatible connection kit, a critical feature for modern technical facilities management and HVACR system safety. Contractors should note the angle pattern configuration, which facilitates efficient drainage piping. This valve is intended for emergency relief only and must not be used as an operating control.
Key Benefits for Technicians- High BTU Rating: Rated for systems up to 5,370,000 BTU/hr, ensuring compliance with large-scale boiler overpressure requirements.
- Advanced Seat Design: The raised seat prevents sediment and mineral deposits from fouling the seal, maintaining a reliable shut-off after automatic reseating.
- Corrosion Resistance: Lead-free copper silicon alloy or bronze construction and a high-temperature resistant water seal protect internal spring parts from fluid contact.
- Flood Detection Ready: Includes a factory-installed sensor for SentryPlus Alert technology to provide real-time notification of discharge line activity.
Is this valve suitable for potable water systems?
No, the Watts F276050 is designed for non-potable hot water heating and space heating boiler applications only. For domestic hot water supply requiring lead-free compliance, use the LF174A series.
Can the pressure setpoint be field-adjusted?
This 125 PSI relief valve is factory-set and sealed to maintain its ASME rating. Attempting to adjust the spring tension in the field will void the certification and compromise system safety.
What size should the discharge line be?
The discharge piping must be the same size as the valve outlet (1-1/4" NPT) and should be pitched downward to a safe place of disposal to prevent water from being trapped in the valve body.
