5 INSTALLATION
WARNING: Plastic liners on the valves require
particular protection before/during installation;
therefore:
CAUTION: Transport valve to installation site in
protective package if available. If flange covers are
present, remove them only immediately before
installation.
5.1 Check valve for transport damage. Do not install
damaged valves.
Ensure that only valves are installed whose pressure
class, type of connection and connection dimensions
satisfy the installation conditions. See Markings and
Valve specifications.
DANGER: Do not install valves whose approved
pressure and temperature range is not sufficient for the
operating conditions. The limits for use are marked on
the valves. Moreover, use only valves suitable for the
operating medium in question.
Failure to observe these precautions can pose a danger
for the user and cause damage to the piping system.
5.2 The actuator must correspond to the intended
connections and control data.
5.3 The connection flanges must be inline with the valve
connections and parallel. Connection flanges which
are not parallel can damage the plastic liner during
installation!
5.4 Before installing, thoroughly clean the valve and the
pipeline to remove any contamination, particularly hard
foreign particles.
5.5 In particular, it is necessary to ensure that the sealing
surfaces on the flange connection are free of all
contamination when installing.
5.6 When inserting the valve into a pipeline already
installed, the distance between the ends of the pipeline
must be sufficient to prevent damage to any of the
sealing surfaces.
WARNING: Tighten all flange connections to the
torques specified in Tables 1a or 1b. When using
torque wrenches, ensure that these torques are
reached, however not exceeded.
The values in the table apply for flanges according to
EN1092, PN10/16 for a maximum operating pressure
of 10 bar. Values for other flanges can be obtained from
the manufacturer.
5.7 Valves are to be installed in the appropriate flow
direction. The flow direction is indicated by an arrow on
the valve.
5.8 Observe the appropriate instructions for connecting
the actuator to the valve. Control valves are equipped
with a positioner. The connections for air supply and
signals are marked clearly (see also applicable
operating instructions for the positioner). The
maximum air supply is specified on the name plate. If
the air supply exceeds the pressure specified on the
rating plate, a pressure reduction station is required. If
no instrument air is available, install an air filter in the
air supply line if required.
5.9 After completion of installation, perform a function test
with the control signals: The valve should open and
c l o s e p r o p e r l y c o r r e s p o n d i n g t o t h e c o n t r o l
commands. Always eliminate any recognizable
malfunctions before startup. See also applicable
sections in maintenance regulations for this valve
series.
DANGER: Improperly executed control commands can
pose a danger for life and limb and damage to the
piping system and/or the valve.
