6 INSTALLATION
The operator of the system is generally responsible for the dimensioning of the piping and
the installation of the valve. The function can be affected by planning and installation errors.
6.1 Prepare installation
 Remove the valve from the packaging.
 Check complete valve for transport damage.
 Check the mobility of the discs.
 In case of damage contact the manufacturer.
 Damaged valves / components must not be installed.
DANGER
Incorrectly connected valve
 Installation of the valve may only be carried out by
qualified personnel.
 Flow direction arrow of the valve must match the flow
direction of the pipeline.
 Only valves whose pressure class, chemical resistance,
connection and dimensions correspond to the operating
conditions may be installed.
 Valve may only be used within the intended operating
limits.
 Pipelines must be emptied and cleaned if necessary.
WARNING
Valve handling
 The spring cross is under preload and should only be
released if absolutely necessary. If required, a press
device must be used for this purpose in order to avoid
risks due to high spring forces.
 Special attention must be paid to the risk of crushing or
pinching fingers when testing the mobility of the disc.
DANGER
Accident prevention measures before installation
 Pipelines of the system must be pressureless.
 Ensure that pipelines and valve have cooled down to
lukewarm.
 System must be free of hazardous media.
 System must be switched off and secured against
switching on again.
 If necessary, use the suitable protective equipment.
