We have Ingersoll rand Compressor c25 in order to provides our instrument air header with air required to control all plant instruments. Given that the current throttle limit set to be 290A and the unloading inlet valve position 17%; the compressor suddenly unloadded and the bleed valves opens.

how can i solve this problem if the system pressure is 650
Hello Ahmed,

Your description is brief, but I will try.
In case the machine unloaded suddenly and unexpected you might check the following:
1] surge detected by the control system (maybe by instrumentation or controls failure).

2] the machine might have been overloaded (load>290A) in this case the control system might trigger the unload sequence.

3] another system or person might have triggered the unload sequence unwanted.
