Is there a pressure drop chart of the MV-400 series controller available?
For the models: MV-401, MV-402, MV-404
Min. ΔP : 1 bar(d)
Max. ΔP : 7 bar(d)
For MV-405
Min. ΔP : 2 bar(d)
Max. ΔP : 7 bar(d)
Because of the internal spring it takes a minimum ΔP of 1 bar(d) (2 bar(d) for the MV-405) to control the output flow.
The pressure loss is minimal because of the internal spring and membrane.
