Shipment and on-site transport
b) Type 3381-3-X with valve
See Fig. 4-2
NOTICE
!
Incorrect lifting will damage the valve.
The valve bonnet (yoke) may become dam-
aged through the introduction of a bending
moment.
Î Attach the slings in such a way that the
mid‑axis of the valve and the mounted
silencer is always in the horizontal
position and that the axis of the plug/
actuator stem remains in the vertical
position during lifting.
NOTICE
!
Incorrect mounting before lifting will dam-
age the valve.
Î The valve and silencer must be bolted to-
gether with the full tightening torque as
specified before lifting (see the 'Installa-
tion' section).
The Type 3381-3-X Silencer is bolted to the
control valve before they are both installed
into the pipeline (see the 'Installation' sec-
tion).
1. Attach one sling to the flange on the
valve body and to the rigging equipment
(e.g. hook) of the crane or forklift.
2. Attach a sling to the lifting eyelet/eyebolt
on the silencer and to the rigging equip-
ment (e.g. hook) of the crane or forklift.
3. For actuator versions with lifting eyelet,
attach an additional sling to the lifting
4-4
eyelet of the actuator and to the rigging
equipment of the crane or forklift.
NOTICE! This sling must not bear any
load. It only protects it from tilting while
being lifted. Before lifting the control
valve, tighten the sling.
4. Carefully lift the control valve with
mounted silencer. Make sure that the
mid-axis of the valve and the mounted si-
lencer is always in the horizontal posi-
tion and that the axis of the plug/actua-
tor stem is in the vertical position during
lifting.
NOTICE! The valve bonnet (yoke) may
become damaged through the introduc-
tion of a bending moment.
Check whether the lifting equipment and
accessories can bear the weight.
5. Move the control valve including the si-
lencer at an even pace to the site of in-
stallation.
6. Install the valve and silencer into the
pipeline (see the 'Installation' section).
7. After installation in the pipeline, check
whether the flanges are bolted tight and
the valve including the silencer in the
pipeline holds.
8. Remove slings.
