What condition could occur if a pressure relief valve fails to operate properly?

If a pressure relief valve fails to operate properly, excessive pressure buildup can occur. Pressure relief valves are designed to open at a predetermined pressure to allow fluid to escape, thereby preventing the system from exceeding safe operating limits. When the valve fails, it may not open when needed, allowing the pressure in the system to rise uncontrollably. This can lead to potentially dangerous situations, including equipment failure, rupture of pipes, or catastrophic damage to the system.

The importance of the pressure relief valve in maintaining safe operating conditions cannot be overstated; it serves as a critical safety mechanism to manage pressure. Should the pressure exceed safe limits, not only can it damage equipment, but it can also pose serious safety hazards to personnel and the environment.

In contrast, options related to insufficient flow, normal pressure maintenance, or automatic system shutdown do not directly represent the consequence of a relief valve failing to operate. Insufficient flow pertains to not enough liquid moving through the system, while normal pressure maintenance indicates the system is functioning correctly. Automatic system shutdown is generally a response to abnormal conditions but is not the primary result of a failed pressure relief valve.
