Mounting and start-up
Premature wear and leakage due to insuffi -
cient support or suspension.
Attach a suitable support or suspension on
the valve, if necessary.
Vent plugs
Vent plugs are screwed into the exhaust air
ports of pneumatic, electropneumatic and
electric devices. They ensure that any ex
-
haust air that forms can be vented to the at -
mosphere (to avoid excess pressure in the
device). Furthermore, the vent plugs allow
air intake to prevent a vacuum from forming
in the device.
Î
Locate the vent plug on the opposite side
to the workplace of operating personnel.
Î
On mounting valve accessories, make
sure that they can be operated from the
workplace of the operating personnel.
The workplace of operating personnel is the
location from which the valve, actuator and
any mounted valve accessories can be ac-
cessed to operate them.
5.2.2 Additional fittings
Strainer
For certain applications an additional strain-
er can be installed in order to reduce exces -
sive wear.
Insulation
Do not insulate valves mounted to comply
with NACE MR 0175 requirements.
Contact SAMSON’s After-sales Service de -
partment in case that an insulation is re-
quired.
5.2.3 Installing the control
valve
Version with flanges
1. Depressurize the plant and interrupt the
medium flow while the valve is being in-
stalled.
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 flow direction
through the valve. The arrow on the
valve indicates the direction of flow.
4. Make sure that the correct flange gaskets
are used.
5. Bolt the pipe to the valve free of stress.
6. Depending on the field of application,
allow the valve to cool down or heat up
to reach ambient temperature before
start up.
7. Slowly resume medium flow in the pipe-
line after the valve has been installed.
