5 Installation at Site
5.1 General information/Safety regulations
The consultant, construction company or operator are responsible for positioning
and installing the valves. Planning errors and installation errors may impair the
reliable function of the valves and pose a substantial safety hazard.
The valves are supplied ready for operation.
5.2 Installation position
Non-compliance with the following installation instructions may result in failure of
the measuring function!
CAUTION
Flow in opposite direction of flow direction arrow
No measurement possible!
▷
Flow through the valves must be in the direction indicated by the flow direction
arrow cast on the valve body.
The valves can be installed in supply lines and return lines. If the fluid handled is
clean, the valve can be installed in any position in the system. If the fluid handled
contains particles, the valve must not be installed with the handwheel pointing
downwards.
For optimum measuring results, a minimum upstream stabilisation distance of 5x DN
must be maintained upstream of the valve (10x DN downstream of a pump) and a
minimum downstream stabilisation distance of 2x DN must be maintained
downstream of the valve.
For adjusting the volume flow rate, measuring kit can be hired on request.
5.3 Preparing the valve
CAUTION
Outdoor installation
Damage due to corrosion!
▷
Provide weather-proof protection to protect the valve against moisture.
CAUTION
Welding beads, scale and other impurities in the piping
Damage to the valve!
▷ Remove any impurities from the piping.
▷ If necessary, install a strainer.
1. Thoroughly clean, flush and blow through all vessels, piping and connections
(especially of new installations).
2. Check that the inside of the valve is free from any foreign objects. Remove any
foreign objects.
3. If required, install a strainer in the piping.
