Belimo ZG-TF112 Adaptor Kit

The Belimo ZG-TF112 Crankarm Adaptor Kit is a field-proven solution designed to interface TF Series spring-return actuators with damper shafts in jackshaft or short-shaft applications. This kit includes the ZG-113 mounting bracket, providing the necessary offset and structural rigidity for reliable crankarm linkage configurations. Engineered for high-torque transfers in HVAC damper control systems, the ZG-TF112 allows for precise actuator mounting when direct-coupled installation is obstructed. The zinc-plated steel construction ensures long-term durability against mechanical fatigue in commercial air handling units. By utilizing this linkage kit, technicians can convert rotary motion to linear or remote rotary motion, maintaining strict valve or damper positioning accuracy. This kit is essential for retrofitting older pneumatic-to-electric systems or addressing tight-clearance mechanical rooms where standardized mounting is not feasible.

Key Benefits

• Universal Compatibility: Specifically engineered to integrate Belimo TF actuators with standard crankarm linkages.
• Simplified Retrofitting: The included ZG-113 bracket facilitates easier transitions from legacy systems without replacing existing shafts.
• Heavy-Duty Construction: Zinc-plated steel components provide superior resistance to corrosion and mechanical wear in industrial HVAC environments.
• Precision Control: Eliminates excessive play in the linkage, ensuring accurate damper positioning and system efficiency.

Common Questions

Can the ZG-TF112 be used with larger NF or AF series actuators?
No, this kit is specifically dimensioned for the TF series spring-return actuators. Larger actuators require the ZG-100 or ZG-101 series mounting kits to handle the increased torque profiles.

What is the primary function of the included ZG-113?
The ZG-113 serves as the mounting base that stabilizes the actuator, allowing the KH-TF crankarm to translate torque through a linkage rod to the damper shaft.

Is this kit suitable for outdoor installations?
While the hardware is zinc-plated, the assembly should be used within a NEMA-rated enclosure if the TF actuator and linkage are exposed to direct weather or extreme moisture.
