Valley Tool 1415 Shaft

For veteran technicians managing ductwork airflow systems, the Valley Tool 1415 is a critical damper assembly part engineered for heavy-duty HVAC mechanical linkage applications. This 3-hole crank arm is specifically designed for a 1/2" shaft, providing the essential leverage needed to transfer rotational movement from the actuator to the damper blades. Professionals recognize the importance of precise positioning; the three-hole configuration offers adjustable radii to fine-tune the movement range and torque, ensuring the actuator linkage operates within optimal specifications.

Forged from high-grade alloy and plated with a ROHS-compliant bright zinc finish, the Valley Tool 1415 3-hole crank arm for 1/2 inch shaft is built to withstand high-pressure industrial environments. This corrosion-resistant damper linkage component maintains structural integrity against the constant cycling of air control systems. Whether you are performing a field replacement or a new HVAC damper repair, this arm ensures a slip-free connection and reliable operation in diverse thermal conditions.

• Universal HVAC Compatibility: Fits any standard 1/2" diameter damper shaft for seamless field integration.
• Variable Stroke Adjustment: The 3-hole design allows for adjustable mechanical advantage to meet specific damper stroke requirements.
• Durable Zinc Protection: Features a ROHS-compliant finish that resists oxidation and wear in harsh mechanical rooms.
• Standardized Linkage: Designed to connect easily with standard ball joints, swivels, and push rods used in professional damper control.

How do I select the right hole for my linkage?
The hole furthest from the shaft provides the longest stroke but less torque, while the inner holes increase torque for heavier damper sections with a shorter arc. Most HVAC technicians use the middle hole for standard multi-blade damper configurations.

Is this compatible with Belimo or Johnson Controls actuators?
Yes, provided the actuator is equipped with a 1/2" crank arm adapter. This is a standard damper part used widely across major OEM control setups.

What is the typical weight and size of this part?
The 1415 is a compact, high-strength arm weighing approximately 0.18 lbs, ensuring minimal rotational inertia during high-speed actuation.
