Safety instructions and measures
Intended use
The SAMSON Type 3278 Actuator is mounted on butterfly valves and other final control ele-
ments with rotary closure members. In combination with the valve, the actuator is used to
shut off the flow of liquids, gases or vapors in the pipeline. The actuator is suitable for both
throttling and on/off service. The actuators can be used in processing and industrial plants.
The actuator is designed to operate under exactly defined conditions (e.g. thrust, opening
angle). Therefore, operators must ensure that the actuator is only used in operating condi-
tions that meet the specifications used for sizing the actuator at the ordering stage. In case
operators intend to use the actuator in other applications or conditions than specified, con-
tact SAMSON.
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
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 must be observed. According
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 spe-
cialized training, their knowledge and experience as well as their knowledge of the applica-
ble standards.
