Pressure Loss
In case of two-pipe heating system it is necessary to calculate the correct level of valve presetting and specify this in the project documentation to ensure a proper function of the heating system. This must be kept by the installer during installation of the heating system.
In case of one-pipe heating system it is necessary to set the valve at level 6. For adjusting the required mass flow in the radiator we recommend to use the compact connecting fitting with a fixed or adjustable flow volume of water in the radiator.
