  10. Installation ofValve Body • Connect housing to the unions by means of the union-nuts ATTENTION: Pipeline sections must be parallel and co-axial The pipeline must not subject the valve to any bending or shear efforts

  11. Installation ofValve Body • Connect the blank aluminum tag to the valve body by means of the plastic tie

  12. Flushing the System Once all the valve bodies have been installed, flush the system. A correct flushing operation is important in order to remove any debris that could prevent a correct functioning of the regulating cartridges.

  13. Installation of the Regulating Cartridge After flushing the system, the regulating cartridges can then be inserted into their corresponding valve bodies. • Remove the valve housing from the pipeline • Open kit KRR2

  14. Installation of the Regulating Cartridge • Slip the O-ring onto the cartridge • Insert the cartridge with the O-ring into the housing of the valve • Insert the distance ring

  15. Installation of the Regulating Cartridge OBS #1: • The O-ring does not need to be inserted all the way up to the cartridge shoulder • The cartridge body is slightly conical: for an easier insertion into the housing, slip the o-ring just half way up the cartridge

  16. Installation of the Regulating Cartridge OBS #2: • A laser-marked arrow indicates the correct direction in which to insert the distance ring Laser-marked arrow indicating insertion direction

  17. Installation of the Regulating Cartridge • Re-install the housing with the cartridge on the pipeline • ATTENTION: ensure that the arrow marked on the body is pointing in the same direction of the flow Forged arrow indicating correct flow direction
