Table 1 – Designation of the butterfly valve
Keep the labeling on the valve body and on the nameplate to ensure that the valve can be identified at all times.
3. Transport and storage
Butterfly valves must be carefully handled, transported and stored:
Store the valve with its protective packing and/or with its protective caps in place in the end connections. Store and
transport the butterfly valves that weigh over approx. 10 kg on pallets (or a similar type of support) right up to the point of
installation. The packing is designed to protect the valve’s internal parts against being damaged.
Store the valve in a closed room before it is installed. Protect it against damaging influences such as dirt or moisture.
Make sure, in particular, that the facings of the flanges are not damaged through mechanical or other influences. Do not
stack butterfly valves!
As a rule, butterfly valves are delivered in the closed position. Store the valves in the condition they were delivered in. Do
not operate the valve.
4. Installation in the pipeline
4.1
General
The same instructions apply for installing the butterfly valves in the pipeline as for connecting pipes and similar pipeline
equipment. The following instructions additionally apply for butterfly valves. Also observe section 3 for transporting the butterfly
valve to the point of installation.
