What is the primary function of a pressure relief valve?

• A. To increase water pressure in the pipes
• B. To release excess air or water pressure
• C. To restrict flow in fire protection systems
• D. To measure water supply in the system

Answer: (B)

The primary function of a pressure relief valve is to release excess air or water pressure within a system. This is crucial for maintaining safety and integrity in piping systems, especially in fire protection systems where pressure can fluctuate due to various factors such as temperature changes or water supply variations. By releasing excess pressure, the valve helps prevent potential failures or damage to the system, which could arise from overpressure situations. This function is essential because high pressure can lead to leaks, ruptures, or even catastrophic failures that compromise the entire system's effectiveness. The pressure relief valve acts as a safeguard, ensuring that the system operates within its designated pressure range and protecting both the infrastructure and users from the hazards associated with excessive pressure.
