Uses and function
Uses
The unit is intended for operating ball
valves, butterfly valves or other valves
with an operating angle between 0°
and 360°.
Function
In the body of the unit (2), there are
sub-assemblies which impart a rotary
motion to the operating shaft (5).
By switching on the electric motor (7),
the gear wheel on the released electric
brake (3) is rotated by timing belt (9).
This motion is transmitted by the
planetary gear (1) and gears in the
lower part of the unit to the operating
shaft (5).
According to the actuator model, vari-
ous types of power supply and different
voltages may be used.
