Watts 0275614 Relief Valve
The Watts 0275614 (Model 375XL) is a high-capacity pressure relief valve designed specifically for hot water heating boilers and hydraulic systems. Featuring a 1 1/4 inch NPT threaded inlet and a 1 1/2 inch NPT outlet, this valve is factory-set to a 35 PSI relief pressure, providing critical overpressure protection. Utilizing a bronze body construction and a silicone rubber disc, it ensures a tight seal and reliable reseating after discharge. For contractors managing large-scale commercial or industrial boilers, the Watts 375XL series is the industry standard for high BTU discharge capacities. This ASME Section IV certified component is essential for maintaining system integrity and meeting strict mechanical codes. Its high-volume discharge capability prevents pressure excursions from damaging boiler heat exchangers or piping networks. This valve is engineered for durability in high-temperature environments, ensuring long-term performance under demanding hydronic cycles.
Key Benefits
- High BTU Rating: Optimized for high-capacity hot water boilers requiring rapid pressure stabilization.
- Corrosion Resistance: Heavy-duty bronze body prevents pitting and scale buildup in aggressive water conditions.
- Precision Calibrated: Factory-set at 35 PSI to ensure immediate response to overpressure events.
- ASME Certified: Meets National Board requirements for safety and performance reliability in hydronic systems.
Common Questions
Can the 35 PSI setting be adjusted in the field?
No, the Watts 0275614 relief valve is a factory-set safety device. Field adjustments are not recommended as they can void the ASME certification and compromise system safety.
Is this valve compatible with potable water systems?
No, this specific model is designed for non-potable hot water heating applications. For domestic hot water tanks, a T&P (Temperature and Pressure) valve is required.
What is the proper orientation for installation?
To ensure proper mechanical operation and drainage, the valve must be installed in a vertical position with the discharge piping directed downward to a safe point of disposal.
