The feed control valve of the reformation unit is making a lot of noise
Thread Content
The control valve is making a lot of noise, and there is some vibration in the pipeline. The opening degree of the on-site control valve is also quite high, but there is still a lot of noise. What could be the reason? The medium in the pipeline is normal temperature naphtha
Having not experienced such a situation, it would be best to provide parameters such as temperature, pressure, and flow rate before and after the valve; only with data can further analysis be carried out!

Open the valve stem of the control valve to a certain degree and see if there are still any abnormal noises; it might be sounds caused by the flow rate acting on the control valve element!
The control valve has no flow limitation, but it’s possible that the flow meter is restricting the flow; we have encountered this situation before.
The poster could provide the specific pressure and flow parameters, as well as the pressures and temperatures before and after the valve, so that the issue can be analyzed better. Also, what does the sound like?
The pipe supports installed in the pipelines upstream and downstream of the control valve may not be appropriate; adding additional pipe supports could be effective； Also, the secondary line may have a slight leak, and this can happen as well.
It seems to be the sound generated as the medium flows, causing vibrations and unusual noises; will installing pipe supports solve this issue?
Please confirm what the opening degree of the control valve is? Is the abnormal noise caused by an excessive pressure drop before and after the valve? If the opening degree of the control valve permits it, try to reduce the pressure before the valve to see if that helps
