What should be avoided when installing high-pressure safety valves on a boiler?

• A. Using valves of varying sizes
• B. Installing a smaller valve with a capacity less than 50%
• C. Ensuring both valves are new
• D. Using manual valves instead of automatic

Answer: (B)

When installing high-pressure safety valves on a boiler, it is crucial to ensure that the valves have adequate capacity to handle potential pressure surges. Choosing a smaller valve with a capacity less than 50% of the system's required safety valve capacity can lead to insufficient relief of pressure in the event of a system failure, which could result in dangerous conditions, including potential boiler explosions or damage. The selection of the correct size and capacity for safety valves is governed by industry standards and codes, which specify that safety valves must be able to relieve pressure at the required rate to maintain safe operating conditions. A valve that cannot adequately handle the pressure buildup poses a significant risk to the boiler system. Therefore, ensuring that safety valves are properly sized and able to manage expected pressures is critical for maintaining safety and compliance with regulations. While using valves of varying sizes, ensuring that valves are new, or using manual valves could also present challenges, the most critical factor for ensuring safety is the capacity of the safety valves themselves.
