A drop in pump capacity is the most direct and noticeable symptom of an open PRV. There is a change to the sound the pump makes, but this is less noticeable. Return-to-tank relief valves or external PRV's on the discharge piping can be fitted with flow detectors or other instrumentation to make a better determination of a valve in bypass.
@@raykinsella5081 My pumps PRV is fit on the casing itself; not a return-to-tank type. And I asked because once the discharge valve malfunctioned and didn't open due to which PRV acted (without our knowledge). We could know only when the temperature of diesel (liquid handled) increased
What if the pump head is quite small to begin with? That means the discharge pressure will not be much higher than the suction pressure, which means that during relief (relief = disch pres x 1.5), the valve will be required to overcome a high backpressure...which is always a challenge for a direct acting relief valve...how will that work?
This type of relief valve is not intended to be relieving as part of normal operation. If differential pressure is low, the valve will remain closed. It is typically there to limit the differential pressure should an upset condition occur (i.e. a closed discharge valve or blockage in the downstream piping). I think you may be thinking of pressure regulating valves, not pressure relief valves.

beautiful animation. curiosity: which software to create and animate 3d objects did you use?
how test preesure... BARG if normal close without. iam test 0.3 BARG poopet is leak bubble open here
Have you providing any course?
How can we know if the PRV is open or close?
