Watts 0275824 Valve
Ensure critical over-pressure safety for commercial heating systems with the Watts 0275824 (Series 174A-M1), a high-capacity 1-1/4 inch NPT pressure relief valve specifically engineered for hot water space heating boilers. This ASME Section IV certified valve is preset to 50 PSI and provides a discharge capacity of 2,459,000 BTU/hr, making it a reliable choice for large-scale hydronic applications. The bronze body construction is designed to resist corrosive water conditions, while the non-metallic disc-to-metal seating ensures a tight seal and prevents sticking or freezing over time.
Designed with maintenance in mind, the Watts 174A 1-1/4 features a unique "above drain" seat design that prevents sediment from fouling the valve and ensures water cannot be trapped around the spring. The non-mechanical seat-to-disc alignment provides consistent reseating even after emergency discharge. This model includes SentryPlus Alert flood sensor technology, which, when paired with a compatible connectivity kit (sold separately), enables remote monitoring and alerts through building management systems (BMS) to mitigate potential flood damage from excessive relief discharge.
Key Benefits:- ASME Rated Capacity: Certified for high-output boiler protection up to 2,459,000 BTU/hr at 50 PSI relief settings.
- Enhanced Corrosion Resistance: Durable bronze body and stainless steel spring withstand harsh hydronic environments.
- Flood Sensor Connectivity: Integrated sensor detects unwanted discharges to prevent property damage through real-time alerts.
- Reliable Reseating: Non-mechanical alignment mechanism prevents the disc from sticking or freezing after operation.
- Sediment Protection: Raised seat design isolates the spring from discharge and prevents sediment buildup from compromising the valve seal.
Is this valve suitable for potable water applications?
No, the Watts 0275824 is specifically designed for non-potable hot water heating and domestic supply boiler applications and does not meet lead-free requirements for drinking water systems.
Does this unit include the activation kit for the flood sensor?
The integrated sensor is included, but the SentryPlus Alert connection kit required to relay signals to a BMS or Wi-Fi network must be purchased separately.
Can the pressure set-point be adjusted in the field?
This valve is factory-calibrated to 50 PSI. These safety devices should not be tampered with or adjusted; if a different relief pressure is required, the appropriate factory-set model must be selected.
