Ensure that the central nozzle and the atomisation cone correspond to the axis of the 
piping. The cooling medium must always be injected in the direction of flow of the medium ! 
 
1.6 Preparation for installation in the pipeline 
 
The sealing and functional check as well as the quality assurance checks carried out in the 
factory ensure the version of the control valve fully corresponds with the version specified in 
the supply contract. The model number and data required for operating the valve and drive 
are noted on the nameplate. The achievable stroke can be read on the driving starting 
pillar/yoke. 
 
 
Before the installation, the pipelines must be carefully cleaned.
 
 
1.7 Installation of the SCHMIDT valve 
 
Checklist: 
 
• Does the name plate agree with the operating data of the system?
Non-agreement can lead to considerable damage of the injection nozzle valves, for 
which the manufacturer accepts no liability ! 
• Is sufficient space available at the installation location for problem-free installation and
removal?
• Have the pipelines been cleaned before the installation?
Carefully remove any foreign bodies !
• Has the control valve been depreserved and cleaned before installation?
• Does the direction arrow attached to the body agree with the direction of flow?
• Do any unallowed voltages occur during installation and operation of the control valve?
Perpendicularity of the flange required !
• Does the spacing of the pipe ends correspond to the overall valve length?
 
 
If the aforementioned points are fulfilled, the control valve can be inserted in the pipeline 
and screwed together with the connecting material ( seals, screws, nuts - provided by the 
builder). Afterwards, the piping of the drive with the plant air in pneumatic actuators or the 
wiring of the electrical actuators can be carried out according to the electrical block diagram 
located in the removable drive hood or in the drive manufacturer documentation.
