gearboxes are a useful addition to the AUMA product ranges.
They reduce the required input torques to convenient rim pull
for manually operated valves.
together with multi-turn actuators SA, they increase their
torque range. Often a small multi-turn actuator combined with
a spur or bevel gearbox is the less expensive solution compared
to a large multi-turn actuator, provided the longer operating
time can be accepted.
gearboxes displaces additionally the direction by 90°. As
a result e.g. depending on spatial conditions the mounting
of an actuator only then becomes possible.
