When pressurizing a system with nitrogen, what should be installed in the line downstream from the pressure regulator?

• A. A filter drier
• B. A pressure gauge
• C. A relief valve
• D. A shut-off valve

Answer: (C)

When pressurizing a system with nitrogen, it is essential to ensure safety and regulation of the pressure within the system. Installing a relief valve downstream from the pressure regulator is critical for preventing overpressure scenarios. A relief valve serves as a safety device that automatically releases pressure to keep the system pressure from exceeding a specified limit. This is particularly important when working with refrigerant systems or any pressurized equipment because excess pressure can lead to system damage, leaks, or even catastrophic failure. The relief valve essentially acts as a safeguard, allowing for safe handling and maintenance of the system under pressure conditions. It ensures that, in the event of a failure or malfunction in the pressure regulating system, excess pressure can be released safely without risking harm to equipment or personnel. Therefore, having a relief valve installed is a necessary precaution when dealing with pressurized systems.
