Valley Tool Damper Parts 1403-L Long Crank Arm 3/8" Shaft

The Valley Tool Damper Parts 1403-L Shaft Long Crank Arm is used in equipment control assemblies to transmit motion from an actuator to an air control motor. It is built for a 3/8" shaft connection with an extended arm design that supports controlled angular movement in linkage setups. The component is positioned within equipment where it connects actuator output to damper blades, allowing airflow regulation inside ductwork, air handling units, and ventilation networks. It plays a structural role in converting actuator rotation into damper positioning, ensuring coordinated air flow control in systems used across commercial and industrial ventilation setups and air distribution units.
