What function does a pressure relief valve serve in a propane system?

• A. Increase pressure
• B. Decrease temperature
• C. Release excess pressure
• D. Measure pressure

Answer: (C)

A pressure relief valve is a crucial safety component in a propane system. Its primary function is to release excess pressure that accumulates within the system. This is important because an increase in pressure beyond safe operating limits can lead to dangerous situations, including potential explosions or equipment damage. The pressure relief valve is designed to open at a predetermined pressure level, allowing propane to escape safely and thereby preventing the pressure from reaching critical levels. This protective measure ensures the integrity of the system, helping to maintain safe operating conditions. Options such as increasing pressure or measuring pressure do not align with the function of a pressure relief valve, as its sole purpose is to relieve pressure, not to enhance it or take measurements. The option of decreasing temperature also does not relate to the primary responsibility of a pressure relief valve, as its design and function focus on managing pressure rather than temperature control. Thus, the most accurate and relevant choice is the release of excess pressure.
