Fault in GD4-300/4.5-135 diaphragm compressor

Our unit uses this compressor; the designed outlet pressure for the first stage is 15 kilograms, but in reality it is 30 kilograms. The outlet pressure of the second stage is roughly equal to that of the first stage, meaning that no pressure increase occurs in the second stage. The outlet temperature of the first stage is 150 degrees. Could some expert help us figure out what the cause of this is.

Generally, there is a problem with the gas valve, that is, an issue with the exhaust at the second stage; replacing it will resolve the problem

This issue with this model is mainly likely to be a problem with the air valve
