Electric Actuators - Free Shipping!

These Belimo electric actuators are two position spring return actuators for the On-Off, Fail-Safe control of HVAC Control Dampers and Operable Louvers. They are designed to be mounted directly to the damper shaft, or jackshaft. In applications where direct mounting is not possible, a crank arm and mounting bracket can be supplied to facilitate installation. The spring return system provides constant torque, to the item being controlled, with, and without power applied to the actuator. These actuators also provide 95° of rotation and are provided with a graduated position indicator showing 0° to 95°.
