What component is designed to open to relieve pressure when the limit exceeds the safe limit?

• A. Safety Valve
• B. Pressure Relief Valve
• C. Safety Relief Valve
• D. Exhaust Valve

Answer: (C)

Overpressure protection relies on devices that automatically open when pressure goes beyond a safe threshold. The safety relief valve is built to sense that excess pressure and open to vent the system, releasing gas or steam to bring pressure back to a safe level. This automatic relief prevents damage or an explosion and is exactly what the wording implies about relieving beyond the safe limit. An exhaust valve is used to vent exhaust gases in engines and isn’t a protective overpressure device. While safety valves and pressure relief valves perform similar relief functions, the term that emphasizes opening to protect the system when limits are exceeded is safety relief valve.
