Testing Procedure :
Online testing of steam relief safety valves is an accepted method of Relief Valve testing for all type of safety relief valves.
A load cell is mounted with electronic DC moter puller on the valve's stem top.
This pulls the stem thereby trying to lift the disc.
The net result is that the valve pops at a pressure set pressure less electronic pressure calculated on the basis of disc area.
We do not have to actually raise system pressure to the set point of the Relief Valve.
But , Electronic Test puller can be apply more than 100 kg/cm2 pressure on the valve disc depending on disc area.
Still, since the system pressure remains very less than set pressure when the valave pops, it is safer. This method is normally used for stem safety relief valves.
All Type of safety valves, Safety Relief Valves, Pressure Relief Valves can be test.
