Transport and storage
Piggable ball valves must be carefully handled, transported and stored:
Ö
Store the valve with its protective packing and/or with its protective caps in place in the end connections. Store and transport the
piggable ball valves that weigh over approx. 10 kg on pallets (or a similar type of support) right up to the point of installation.
Ö
Store the valve in a closed room before it is installed. Protect it against damaging influences such as dirt or moisture.
Ö
Make sure, in particular, that the actuator and the end connections intended to connect the valve to the pipeline are not damaged
through mechanical or other influences.
Ö
As a rule, piggable ball valves are delivered in the completely open position. Store the valves in the condition they were delivered
in. Do not operate the actuating device.

Installation in the pipeline
4.1 General
The same instructions apply for installing the piggable ball valves in the pipeline as for connecting pipes and similar pipeline equipment.
The following instructions additionally apply for piggable ball valves. Also observe section 3 for transporting the piggable ball valve to the
point of installation.
Note
The mating flanges must have smooth facings
Contact the manufacturer if you intend to use other flange forms.
Danger
If an actuator unit has been mounted subsequently, torque, direction of rotation, operating angle as well as the final
positions OPEN and CLOSED must be adapted to the piggable ball valve.
Failure to follow these safety precautions may result in personal injury and can damage equipment installed in
the pipeline.
Warning
The actuating device is set for the operating data specified in the order.
Do not alter the settings for the final positions OPEN and CLOSED
without the manufacturer’s prior consent.
Warning
Only for piggable ball valves with electric actuator:
Make sure that the actuator is switched off in the final positions by the
limit switch’s signal
. If the actuator is switched off
in an intermediate position by the
torque switch’s signal
, this signal should be used additionally for fault indication.
Remedy any faults as quickly as possible. See section 7 <Troubleshooting>.
See the instructions for the electric actuator for further details.
The following warnings are to be observed for actuators:
Warning
Actuators are not designed to be used as step-ladders:
Do not apply any weight/load to the actuators. This can damage or destroy the piggable ball valve.
Warning
Actuators that weigh more than the piggable ball valve:
Support any actuator which due to its size and/or mounting situation would otherwise cause the valve to bend under the
load.
4.2
Installation instructions
Ö
Transport the valve in its original packaging right up to the point of installation. Remove packaging first at the point of installation
to protect it from dirt.
Ö
Check valve and actuator for signs of damage that may have occurred during transportation. Do not install a damaged piggable
ball valve or actuator.
Ö
Make sure that only piggable ball valves are installed when their pressure rating, end connections and face to face dimensions
match the conditions of application. See the designation of the piggable ball valve.
Danger
Do not install a piggable ball valve if its permissible pressure/temperature ranges do not apply to the operating conditions.
The limits of application are marked on the valve, see section 2.4 <Designation>. The permissible range is determined in
section 1 <Intended use>.
Failure to follow these safety precautions may result in personal injury and can damage equipment installed in
the pipeline.
