ESBE ARC/ARD Series High Torque Actuators

ESBE ARC-ARD Series of Actuators

High torque rotary actuators

The ESBE ARC/ ARD series of high torque rotary low voltage motorized 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 motorized 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.

Features and benefits

Increased torque ability (in comparison to 90 Series motorized actuators), to overcome a high differential pressure across the valve.

Applications

3 Way Mixing or Diverting

When the ARC/ ARD actuators are assembled to the ESBE Type F 3-way valve, the actuator provides rotation of the valve to control the flow 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

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.
