'0' on the travel indicator scale with the tip
of the stem connector clamp (see Fig.5-5).

2. Loosen the screws on the travel indicator
scale.
3. Align the travel indicator scale.

by tightening the screws.
5.3.3 Installing the valve into
the pipeline
Premature wear and leakage due to
insufcient support or suspension.
Î Support or suspend the valve sufciently
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 ow direction through the valve. The
arrow on the valve indicates the direction
of ow.
5. Make sure that the correct ange gaskets
are used.
6. Bolt the pipe to the valve free of stress.
