Watts 0121560 Valve
The Watts 0121560 is a high-capacity 2-inch LF174A boiler pressure relief valve designed specifically for large-scale hot water space heating systems. Engineered for demanding commercial environments, this ASME Section IV certified valve features a massive steam discharge capacity of 8,215,000 BTU/hr at a 80 PSI set pressure. The lead-free copper silicon alloy body ensures structural integrity and compliance with modern safety standards, while the NPTF female connections simplify integration into high-performance hydronic loops. Unlike standard valves, the Watts LF174A utilizes an "above-the-drain" seat design to prevent sediment buildup from fouling the disc-to-metal seating surface. The non-mechanical seat-to-disc alignment prevents sticking or freezing during critical expansion events, ensuring reliable emergency pressure relief. For proactive system monitoring, this unit is equipped with a SentryPlus Alert flood sensor, which can be integrated into a Building Automation System (BAS) via an optional connection kit to notify technicians of excessive discharge before water damage occurs.
Key Benefits for HVAC Contractors- Extreme Output Rating: Rated for up to 8,215,000 BTU/hr, making it suitable for high-output commercial boilers.
- Advanced Flood Detection: Integrated SentryPlus Alert sensor allows for real-time monitoring of valve activation and discharge events.
- Superior Seat Protection: The raised seat design isolates spring components and prevents mineral deposits from trapping water or obstructing the seal.
- Code Compliance: Lead-free construction and ASME Section IV rating meet strict engineering specifications for domestic and commercial heating applications.
- Technical Durability: Features a high-temperature resistant water seal and a stainless steel spring for long-term performance in corrosive conditions.
What is the primary application for the 2-inch LF174A 80# valve?
This valve is designed for emergency safety relief in hot water heating boilers. It is not intended for use as an operating control. It should be used to protect the system when thermal expansion exceeds the 80 PSI threshold.
How does the SentryPlus Alert sensor work?
The sensor captures discharge events and, when paired with a compatible activation kit (sold separately), communicates via RS-485 Modbus or Wi-Fi to alert maintenance teams of system issues.
What are the installation requirements for the discharge line?
The discharge piping must match the 2-inch valve outlet size exactly and must be pitched downward to a safe, visible point of disposal to prevent water from being trapped against the seat.
