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 flow or temperature requirement in a mixing or
4-way Mixing Application
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.
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.
