8 Installation

8.1 General notes

The same installation regulations apply to a valve as to the system into which it is installed. The following
additional notes apply:
» Section Transport and storage should also be observed during transport to the installation site.
» The installation site to allow perfect functioning of a valve should be a section of pipe without any flow
disruptions, without any angles and without any restrictors/shut-off devices close to the valve, either
upstream and 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 valve, particularly
those with an eccentric mass. If required the pipeline may have to be properly supported on both sides next
to the valve (or at the valve itself) – particularly in the case of valve with a substantial mass and especially if
vibrations are to be expected in the system.
» When the valve is supported, it is important to check that all functioning parts (adjusting screws, springs)
remain capable of moving freely and are not blocked.
» The valve must not be coated with thermal insulation.
NOTICE
Possible damage due to overheating
Failure to observe this instruction can cause damage to the valves and thus to the piping
system.
» A valve that is operated at a medium temperature above 130°C needs undisrupted
removal of heat if it is to function perfectly.
» The upper limit of the permissible operating data, pressure and temperature, must not be
exceeded.
» 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 valve.
NOTICE
Contaminated medium can damage the valve or impair its function
A filter or screen can be used to protect the valve in the pipeline section. The mesh size of
the filter is determined by the operator in accordance with the operating conditions.

8.2 Installation preparations

» It is necessary to ensure that a valve is not installed unless it matches the operating conditions in terms of
function, pressure and temperature range, body material as well as connection type and dimensions.
