ESBE ARC/ ARD High Torque Rotary
Actuator Series
Features:
The ESBE ARC/ ARD series of high torque
rotary low voltage actuators provide a 90°
operating range of rotation. This series of
actuators is suitable for assembly to ESBE
series 3F and 4F valves that range from
2” to 6” in size and alternatively applied
as damper actuators. The appropriate
mounting kit to assemble the actuator
to either an ESBE valve or a damper are
included. For the ARD actuator series,
incorporated into its design is a spring
return, i.e. safety function, to rotate the
valve to a close position in the event of
power failure or removal of signal.
• Increased torque ability in comparison to series 90 actuators
to overcome a high dierential pressure across the valve.
ARC: 265.5 in-lb (30 Nm) / ARD: 177 in-lb (20 Nm)
• Included mounting kits specic for ESBE Type F valves
and damper square or round shafts
• Safety spring close function feature ARD269
• 2-point spring close function, ARD257
• Direct mount actuator design with included mounting kit
• Easy manual override of actuator
• Adjustable limitation of 90° rotation on opening or closing
• Low voltage power supply 24VAC or 24VDC,
pre-wired with wire whip

Data sheet ESBE ARC/ ARD High Torque
Rotary Actuator Series
Applications:
3-way Mixing/ Diverting Application
When the ARC/ ARD actuators are assembled
to the ESBE 3-way Type F valve, the actuator
provides rotation of the valve to control the ow
or temperature requirement in a mixing or
diverting application. With the ARD series the
spring function feature is engaged when there is
power loss or the removal of signal. This results in
the actuator rotating the valve to an end position.
4-way Mixing Application
The ARC/ ARD series of actuator can also be
mounted to an ESBE 4-way Type F valve to
provide mixed system temperature regulation
when wired with a system controller.
