Cold Differential Test Pressure - CDTP


It is an adjustment to the set pressure of the valve when it is being set, as it is not at process conditions. The correction can be due to backpressure and/or temperature fluctuations. It can be defined as

(set pressure - back pressure)*correction factor

Correction factor is supplied by manufacturer.
