4.3.4 Lifting points on the bracket
Ö
Fasten a lifting sling to the bracket and the suspension ele-
ment (e.g. hook) of the crane or forklift, see Figure 4-1.
When doing so, ensure the safety, bearing capacity and
length of the lifting slings.
Ö
In the case of an actuator with a lifting eye: fasten additional
lifting slings to the lifting eye on the actuator and on the sus-
pension element.
Ö
Lift the butter fl y valve carefully. Check if the load lifting
equipment holds.
Ö
Move the butter fl y valve at a constant speed to the installation
site.
Ö
Install the butter fl y valve in the pipe, see chapter 5.4
Ö
After installation in the pipe: check that the fl anges are fi rmly
tightened and that the butter fl y valve holds in the pipe.
Ö
Remove the lifting slings.
4.4 Storing the butter fl y valve
Damage to the butter fl y valve due to improper storage!
− Comply with the storage conditions.
− Avoid long storage periods.
− In the case of deviating storage conditions and a longer stor-
age period, contact PFEIFFER.
PFEIFFER recommends checking the butter fl y valve and the stor-
age conditions regularly during a longer storage period.
Ö
In the case of storage prior to installation, the valve should
normally be stored in a closed room where it is protected
against harmful in
fl uences such as impacts, dirt or moisture.
A room temperature of 25°C ±15°C is recommended.
Ö
In particular, the actuator and the ends of the butter fl y valve
to the pipe connection may not be damaged by mechanical
or any other in
fl uences.
Ö
Do not stack the butter fl y valves.
Ö
Prevent condensation in damp rooms. Use a desiccant or
heater.
Ö
The butter fl y valve must be stored in its protective packaging
and/or with the protective caps on the connection ends.
Ö
Butter fl y valves that weigh more than approx. 10 kg should
be stored on a pallet (or supported similarly).
Ö
Butter fl y valves are usually delivered in a closed position.
They must be stored in the position in which they were deliv-
ered. The actuating device must not be actuated.
NOTE
Info
In the case of butter fl y valves that are delivered without an actua-
tor, the valve disc is not secured to prevent it from moving. It must
not opened from the closed position due to external in
fl uences
(e.g. shaking).
Only in the case of butter fl y valves with a pneumatic actuator
does the valve disc protrude outside of the body on body sides in
the delivered state. The packaging on the protruding edge should
protect the valve disc from damage.
Ö
Do not place any objects on the butter fl y valve.
