Valley Tool 1405-L Crank Arm

The Valley Tool 1405-L Crank Arm is a heavy-duty 1/2" shaft long crank arm engineered for precise motion control in commercial HVACR and industrial damper systems. This high-torque linkage component is technically identical to HVAC part 26026G, providing a direct replacement for worn or slipping damper drive arms. Built for damper linkage systems, the 1405-L features a robust set-screw or clamp-down design to secure the 1/2-inch bore to the actuator shaft, ensuring consistent torque transfer without mechanical play. Whether you are performing a damper actuator arm replacement or a custom OEM installation, this long-reach crank arm provides the necessary leverage for larger multi-blade dampers. Its durable construction is designed to withstand high static pressure environments and constant modulation, making it a reliable choice for HVAC mechanical components where smooth operational travel is critical for airflow regulation.

Key Benefits

• Interchangeable Compatibility: Functions as a direct cross-reference for the 26026G, streamlining inventory for service technicians.
• Optimized Leverage: The extended long crank arm profile allows for greater stroke adjustments in complex mechanical linkages.
• Secure Shaft Attachment: Precision-machined for 1/2" shafts to prevent slippage during high-torque damper cycling.
• Industrial-Grade Build: Designed for continuous duty in air handling units and industrial ventilation assemblies.
• Versatile Application: Suitable for OEM retrofits, mechanical motion control, and multi-zone damper configurations.

Common Questions

Is the Valley Tool 1405-L compatible with standard 1/2-inch actuator shafts?
Yes, this 1/2" shaft long crank arm is specifically bored to fit standard half-inch round or D-shaped actuator shafts common in HVACR applications.

Can this be used as a replacement for the 26026G?
The 1405-L is technically identical to the 26026G, making it a reliable damper linkage part substitution without requiring modifications to the existing linkage assembly.

What type of machinery is this crank arm best suited for?
It is primarily utilized in industrial motion control, commercial HVAC damper actuators, and mechanical drive systems requiring precise angular movement.
