What causes inaccurate pressure in the combustion air pipeline?

Thread Content

The pressure before the valve is 5 kPa; after passing through a regulating damper, the pressure drops to 0.4 kPa. In other pipes with identical conditions, the pressure before and after remains at 5 kPa. The flow rate in this pipe is also the same as in the others, and it’s not a problem with the gauge. What’s going on?

Is there a problem with the damper, since there are issues with both the pressure and flow rate?
