What is required if a Pressure Relief Valve (PRV) is to be installed?

A Pressure Relief Valve (PRV) is a critical safety device designed to prevent excessive pressure buildup in piping systems. The installation of a PRV is typically accompanied by the need for a pressure gauge. This requirement arises from the necessity to continuously monitor the system pressure and ensure that the PRV is functioning correctly.

Having a pressure gauge allows operators to see real-time pressure readings within the system, giving them an immediate understanding of the pressures in play. It helps ensure that the PRV will activate when needed, protecting equipment and personnel from potential hazards associated with overpressure situations. Regular monitoring through the gauge aids in maintaining the safety and efficiency of the system.

While other components such as emergency shut-off systems, alarms, and manual overrides may enhance safety and operational procedures, the core requirement linked directly to the PRV's function is having a pressure gauge to continuously monitor system pressure.
