Intended use
The SAMSON Type 2780 Actuator is designed for operating a mounted globe valve. In com‑
bination 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 throttling service and can be used in HVAC plants.
The actuator is designed to operate under exactly defined conditions (e.g. thrust, travel).
Therefore, operators must ensure that the actuator is only used in operating conditions 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, contact

.
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.
