Calibration of the Operation Time
For actuator models equipped with control system, it’s possible to regulate the speed
of actuator operations. The calibration of the operation time is made by Biffi Italia s.r.l.
according to customer requirements and to technical data sheet included in technical
documentation. If necessary, it’s possible to modify or reset the operating time through
the flow regulating valve (optional) placed on inlet of hydraulic cylinder (refer to specific
technical documentation furnished with actuator's scope of supply).
