The Valley Tool Damper Parts 1415 3-Hole Crank Arm is a mechanical linkage part that is used to transfer a motion between an actuator and a damper shaft. The arm is attached to a 1/2-inch diameter shaft and offers three connection holes that enable the adjustment of the position of linkage and movement range damper in HVAC systems. The actuator or control linkage rotational movement is passed through the crank arm to open or close the damper blade attached. It is placed on the shaft in the airflow control assembly and allows the airflow to be adjusted in the duct system under control during equipment operation.
