1 Safety instructions and measures
Intended use
The Type 3379 Pneumatic Actuator with spring-return mechanism is used in conjunction with
a valve as a control unit suitable for the food and pharmaceutical industries. In combination
with the valve, the actuator is used to shut off the flow of liquids, gases or vapors in the pipe-
line. Depending on the version, the actuator is suitable for throttling or on/off service.
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 applications or conditions other than those specified, contact
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.
