actubar is the latest generation in our range of
pneumatic actuators. Externally unmistakable and
technically
unique, the actubar offers new advantages
and uses. Technically speaking, actubar is the
main component in the novel valve control system
bar-vacotrol.
Working together with our directly-mountable system
components as bar-positurn or any other positioner
of the system for actubar is monitoring and regulating
automatic valves economically and effectively.
The hydraulic damper is an additional module for
lengthening the actuation time. An evenly constant
actuation speed is achieved through a piston which
oscillates inside a cylinder containing hydraulic
medium.
Torque remains the same and sudden movements
are avoided so that pipework, valves and actuator
are intrinsically protected.
Hydraulic dampers are deployed where there are
slamming valves such as double-eccentric butterfly
valves and used for preventing water surges.
And furthermore, it is possible to dictate whether
the damping effect is only present at the end
positions or ensures an even speed over the whole
pivoting angle.
Layout of the hydraulic damper is compact. The
module has been designed and constructed to be
secure against manipulation, so that unplanned
changes in the settings are not possible.
This unique construction of the actubar allows addition of components in accordance with VDI/VDE 3847 and best of all, without hoses or pipework.
