New York Low Pressure Boiler COF Practice

To what temperature are relief valves on low pressure boilers rated?

1. 250*F

2. 275*F

3. 300*F

4. 325*F

The correct answer is: 275*F

Relief valves on low pressure boilers are typically rated to operate at a specific temperature that ensures safety and prevents overpressure conditions. In the context of low pressure boilers, the 275°F rating for relief valves is significant because it aligns with the operating parameters of these systems. Low pressure steam boilers are designed to operate at lower pressures, typically not exceeding 15 psi, and the relief valve serves as a critical safety component, ensuring that any excessive pressure or temperature is safely released to avoid potential hazards. The choice of 275°F as the operational rating reflects the need for a safety margin above the maximum operating temperature, allowing for unexpected conditions or fluctuations within the boiler system. This temperature rating is well established in industry standards and codes, ensuring consistency in safety practices across various boiler manufacturers and configurations. Understanding this rating is crucial for boiler operation and maintenance, as it helps ensure that the pressure relief systems function correctly to protect the equipment and personnel involved.
