Installation
Mounting the actuator
Î
To mount the actuator, proceed as de -
scribed in the associated actuator docu -
mentation.
Aligning the travel indicator scale
After mounting the actuator, the travel indi-
cator scale must be aligned. To do so, align
'0' on the travel indicator scale with the tip
of the stem connector clamp (see Fig. 5-5).
1. Move the valve to the closed position.
2. Loosen the screws on the travel indicator
scale.
3. Align the travel indicator scale.
4. Fix the travel indicator scale into place
by tightening the screws.
5.3.3 Installing the valve into
the pipeline
Premature wear and leakage due to
insufficient support or suspension.
Î
Support or suspend the valve sufficiently
at suitable points.
1. Close the shut-off valves in the pipeline
at the inlet and outlet of the plant section
while the valve is being installed.
2. Prepare the relevant section of the pipe-
line for installing the valve.
3. Remove the protective caps from the
valve ports before installing the valve.
4. Lift the valve using suitable lifting
equipment to the site of installation (see
the 'Lifting the valve' section). Observe
the flow direction through the valve. The
arrow on the valve indicates the direction
of flow.
5. Make sure that the correct flange gaskets
are used.
6. Bolt the pipe to the valve free of stress.
7. Attach a support or suspension on the
valve, if necessary.
