How should high-pressure safety valves be configured when used together on a boiler?

• A. Both must be of equal size
• B. The larger valve must have a higher capacity
• C. At least one valve must be smaller
• D. They can differ in size but must meet specific capacity ratios

Answer: (D)

When configuring high-pressure safety valves on a boiler, it is crucial to ensure that they are set up to operate effectively under potential overpressure situations. The correct response indicates that while the safety valves can differ in size, they must adhere to specific capacity ratios. This configuration allows for proper pressure relief without compromising safety or efficiency. Safety valves operate by relieving excess pressure to prevent catastrophic failures in the boiler. When multiple valves are used, it is essential that the combination of their sizes and capacities is capable of handling the possible maximum pressure scenario that the boiler might face. By adhering to specific capacity ratios, you ensure that even if one valve experiences a malfunction or does not fully open, the other valve(s) can adequately manage the pressure relief needs. This careful design consideration helps maintain operational safety while allowing for flexibility in the installation of valves with different capacities.
