What is the temperature limitation for a 150 psi class bronze threaded gate valve according to high-pressure boiler code?

• A. 350 degrees
• B. 375 degrees
• C. 406 degrees
• D. 450 degrees

Answer: (C)

The temperature limitation for a 150 psi class bronze threaded gate valve according to high-pressure boiler code is 406 degrees. This specification is vital because it ensures that the materials used in the valve can withstand the operating conditions without compromising safety and functionality. Bronze valves are commonly used due to their resistance to corrosion and good mechanical properties. However, they have specific limits on both pressure and temperature. The high-pressure boiler code outlines these parameters to prevent failures that could arise from thermal expansion, material degradation, or loss of strength. Operating a bronze valve at temperatures exceeding 406 degrees could lead to softening of the material, which increases the risk of leaks or failure under pressure. Adhering to this temperature limitation ensures that the valve maintains its integrity and operates effectively within the prescribed safety margins of the high-pressure boiler system.
