lot of solutions permit to achieve rotary movements:
racks piston system, crank and slotted link, mechanical
transmission cylinder, etc.
They are however solutions having different parts moving,
with corresponding higher possibilities of damages,
and having a noteworthy dimensioning.
Thanks to a considerable research and to the continuous
cooperation with customers, we tried to reduce to essential
the dimensioning and moving parts.
We planned (patenting it) and built a rotary actuator
that, born to operate throttle and ball valves, proved
particulary up to be used wherever a 90°, 120°,
180° rotary actuation was needful.
functional concept is the very simple one of T lever,
on which it is directly applied the thrust of the feeding
fluid, without dispersive motion transformations.
This allowed to realize constant torques all the actuation
long, keeping characteristics of extreme compactness.
The basic element that allowed us this kind of achievement
is the seal system (patented), composed of a resilient
static gasket, vulcanized directly in the casted body
of the actuator, able to offer a total absence of drainage
and the possibility to be fed both by air and by liquids.
