Mounting and start-up
Shut-off valves
We recommend installing a shut-off valve
both upstream of the strainer and down-
stream of the valve.
Insulation
Only insulate control valves with insulating
section or bellows seal up to the bonnet
ange of the valve body for medium tem-
peratures below 0°C (32°F) and above
220°C (428°F).
Do not insulate valves mounted to comply
with NACE MR0175 requirements and
which have nuts and bolts that are not suit-
able for sour gas environments.
Test connection
Versions with bellows seal tted with a test
connection (G
1
/
8
) at the top ange allow the
sealing ability of the bellows to be moni-
tored.
Particularly for liquids and vapors, we rec-
ommend installing a suitable leakage indica-
tor (e.g. a contact pressure gauge, an outlet
to an open vessel or an inspection glass).
Risk of personal injury due to pressurized
components and process medium escaping
under pressure.
Do not loosen the screw of the test connec-
tion while the valve is in operation.
Safety guard
To reduce the crush hazard arising from
moving parts (actuator and plug stem), a
safety guard can be installed.
5.2.3 Installing the control
valve
1. Close the shut-off valve in the pipeline
while the valve is being installed.
2. Remove the protective caps from the
valve ports before installing the valve.
3. Lift the valve using suitable lifting equip-
ment to the site of installation (see sec-
tion4.2.2). Observe the ow direction
through the valve. The arrow on the
valve indicates the direction of ow.
4. Make sure that the correct ange gaskets
are used.
5. Bolt the pipe to the valve free of stress.
6. Depending on the eld of application,
allow the valve to cool down or heat up
to reach ambient temperature before
start up.
7. Slowly open the shut-off valve in the
pipeline after the valve has been in-
stalled.
Risk of valve damage due to a sudden pres-
sure increase and resulting high ow veloci-
ties.
Slowly open the shut‑off valve in the pipeline
during start‑up.
8. Check the valve to ensure it functions
properly.
