7 Installation

7.1 General notes

The same installation regulations apply to a fitting as to the system into which it is installed. The following
additional notes apply:
» Section Transport and storage [Page 9]
» The installation site to allow perfect functioning of a fitting should be a section of pipe without any flow
disruptions, without any angles and without any restrictors or shut-off devices close to the fitting, either
upstream or downstream (optimum distance = 10 x DN). If this does not apply, the installation situation
should be checked with the plant operator and/or MANKENBERG.
» The statics of the pipeline must be designed so as to take account of the weight of the fitting – particularly
those with an eccentric mass. If required, the pipeline may have to be properly supported on both sides next
to the fitting (or at the fitting itself) – particularly in the case of fittings with a substantial mass and especially
if vibrations are to be expected in the system.
» When the fitting is supported, it is important to check that all functioning parts (adjusting screws, exposed
springs) remain capable of moving freely and are not blocked.
» The fitting must not be coated with thermal insulation.
A fitting that is operated at a medium temperature above 130°C needs undisrupted removal of
heat if it is to function perfectly.
Failure to observe this instruction may cause damage to the fitting and hence in the
caution
pipeline system as well.
» To protect internal functional parts (e.g. the seat) against damage and/or blockages, it may be necessary to
install a strainer and/or filter upstream of the fitting.
The mesh size of the sieve/filter for protecting against aggregates in the pipe section should be
selected by the plant operator according to the operating conditions.
note Failure to observe this instruction may impair the function of the fitting and lead to
damage.

7.2 Installation preparations

» It is neccessary to ensure that a fitting is not installed unless its matches the operating conditions in terms of
function, pressure and temperature, range, body material as well as connection type and dimensions.
No fitting may be operated that does not have a sufficient pressure and temperature range for
the operating conditions – see section Intended use and markings on the fitting.
The manufacturer MANKENBERG should be consulted in the case of any applications outside
danger of
of this range.
fatalities
Failure to observe this regulation may mean danger to life and limb and may cause
damage to the pressure-regulating valve.
» Newly installed tanks and pipeline sections must be thoroughly rinsed and cleaned before commissioning.
» The corrosion protection for the fitting must be adapted to the local conditions.
» A pressure-regulating valve with an exposed spring must be installed in such a way that it presents no risk
of crushing to the operating personnel.

should also be observed during transport to the installation site.
