PRV – Cold Differential Test Pressure;  The Cold Differential Test Pressure (CDTP) of the Pressure Relief Valve (PRV) is a set pressure that is adjusted to be used for the PRV (Bench Testing). Because in actual use conditions, the PRV may be affected by the Backpressure. And the operating temperature. Therefore, when testing at room temperature and without backpressure, it is necessary to adjust the set pressure to compensate for these factors. In other words, the shop test pressure = CDTP. PRV – Cold Differential Test Pressure (Example 1);  An example of a Cold Differential Test Pressure (CDTP) with a backpressure (superimposed) effect. In this case, CDTP is equal to Set Pressure minus Backpressure. Refer to: What … Continue reading What is Cold Differential Test Pressure (CDTP)
