Intended use
TheType3274ElectrohydraulicActuatorisdesignedtooperateamountedglobevalveused
in industrial applications as well as in heating, ventilation and air-conditioning systems.
Three-step control or the version with a positioner ensures a predetermined assignment of the
valvepositiontotheinputsignal.Theactuatorisdesignedtooperateunderexactlydened
conditions (e.g. thrust, travel). Therefore, operators must ensure that the actuator is only used
inoperatingconditionsthatmeetthespecicationsusedforsizingtheactuatorattheorder-
ing stage. In case operators intend to use the actuator in other applications or conditions
thanspecied,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forlimitsandeldsofapplicationaswellaspossibleuses.See
the 'Design and principle of operation' section.
Reasonably foreseeable misuse
The actuator is not suitable for the following applications:
− Useoutsidethelimitsdenedduringsizingandbythetechnicaldata
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts
− Performing service and repair work not described
Qualicationsofoperatingpersonnel
The actuator must be mounted, started up, serviced and repaired by fully trained and quali-
ed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.
