Hi,
Do you have a PM (maintenance program) with regular tests . This should be in place to prevent such event . You need to contact your contractor , for him to evaluate the damage on your system. I don't think anyone can help you without test .
First priority is to solve the issue with the support of your contractor , it could be an equipment failure (PLC , Solenoid, valve .....) .
Good luck

Sir,
Thank U sir for your response.
SOV is being stuck due to fire water quality issue.

Hi,
This should be part of the assessment of what is going wrong! You must have good quality water for your fire water system .
Again ask someone knowledgeable to survey your full system . If your fire fighting system is not not working you are in trouble and you should not operate the plant . Until you have fixed the problem you need to find a plan B ( source of water , connection with fire brigade ....) .
What is going to say your insurance company if you get fire ?
Note : I got similar problem where the water used for fire fighting system was recycled water supposed to be clean !!!!.
Good luck

Hi,
Had the relevant PID already been subjected to a proper risk assessment/analysis, say, FMEA (Failure Modes & Effects Analysis)?
If so, it should had been forecasted to cope with such failure either a redundant SOV being considered or a regular maintenance (open/close the SOV in normal situation) to be done...
