Intended use
The SAMSON Type 3271 and Type 3277 Actuators are designed for operating a mounted
globe valve. In combination with the valve, the actuators are used to shut off the flow of liq-
uids, gases or vapors in the pipeline. Depending on the version, the actuators are suitable
for throttling or on/off service. The actuators can be used in processing and industrial plants.
The actuators are designed to operate under exactly defined conditions (e.g. thrust, travel).
Therefore, operators must ensure that the actuators are only used in operating conditions that
meet the specifications used for sizing the actuators at the ordering stage. In case operators
intend to use the actuators in other applications or conditions than specified, contact SAM-
SON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
Î
Refer to the technical data and nameplate for limits and fields of application as well as
possible uses.
Reasonably foreseeable misuse
The actuator is not suitable for the following applications:
− Use outside the limits defined during sizing and by the technical data
− Use outside the limits defined by the accessories connected to the actuator
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts
− Performing service and repair work not described in these instructions
Qualifications of operating personnel
The actuator must be mounted, started up, serviced and repaired by fully trained and quali-
fied personnel only; the accepted industry codes and practices are to be observed. Accord-
ing to these mounting and operating instructions, trained personnel refers to individuals who
are able to judge the work they are assigned to and recognize possible hazards due to their
specialized training, their knowledge and experience as well as their knowledge of the appli-
cable standards.
