Installation
The work described in this section is only to
be performed by personnel appropriately
qualified to carry out such tasks.
5.1
Preparation for installation
Before mounting, make sure the following
conditions are met:
− The actuator is not damaged.
− The type designation, material and tem-
perature range of the actuator match the
ambient conditions (temperatures etc.).
See the 'Markings on the device' section
for nameplate details.
Proceed as follows:
Î
Lay out the necessary material and tools
to have them ready during mounting.
Î
Check that the vent plugs to be used are
not blocked.
Î
Check any pressure gauges mounted on
valve accessories to make sure they func-
tion properly.
Î
When the valve and actuator are al-
ready assembled, check the tightening
torques of the bolted joints. Components
may loosen during transport.
5.2
Mounting the device
Depending on the version, SAMSON control
valves are either delivered with the actuator
already mounted on the valve or the valve
and actuator are delivered separately. When
delivered separately, the valve and actuator
must be assembled together on site. Proceed
as follows to mount the actuator and before
start-up.
Risk of personal injury due to exhaust air
being vented.
The actuator is operated with air. As a result,
air is vented during operation.
Î
During mounting make sure that vent
openings are not located at eye level in
the work position of the control valve and
the actuator does not vent at eye level in
the work position.
Î
Wear eye and hearing protection when
working near the actuator.
Risk of actuator damage due to excessively
high or low tightening torques.
Observe the specified torques when tighten
-
ing actuator components. Excessive tighten
-
ing torques lead to parts wearing out more
quickly. Parts that are not tightened far
enough may loosen.
Î
Observe the specified tightening torques.
Risk of actuator damage due to the use of
unsuitable tools.
Î
Only use tools approved by SAMSON.
