GENERAL CHARACTERISTICS OF THE ACTUATOR
The (VU) VULCAN actuator is constructed to form part
of a hinged door automation system. Allows the
requirements of standard EN 12453 to be fulfilled.
It comprises a metal body, which contains a hydraulic
pump and a drive piston.
VUA and VU2A Models
(with absorption)
The VUA models have absorption bushing in the
spindle, meaning the speed slows down when
approaching the end of the extension travel (closing
travel, when the actuator is installed for inward
opening), ending in a gentle halt.
The VU2A models have absorption for the two travels
(opening and closing).
VUS Models
(with patented safety system)
The VUS models are fitted with an exclusive safety
system, patented by ERREKA.
This safety system is capable of detecting the collision of
the door against an obstacle, informing the control
panel of this incident, in order to invert operation.
Hence, the VUS models, along with the ERREKA control
panels, allow the requirements of standard EN12453 to
be met without the need for peripheral elements.
