Cartridges are available in different ranges of working differential pressure, the minimum and maximum working therefore depend on the specific cartridge model. A numeric code is marked on the cartridge body univocally identifying it (example for KRR992215.1880).

Install the valve so that the flow direction matches the direction of the arrow indicated on the body of the valve. Perform correct flushing of the plant before installing the cartridge. In order to obtain the best correct flowrate regulation the valves should be installed using pipes of its same nominal size. Water quality should be according VDI 2035. Use at least one strainer for each installation.
