Belimo ZG-LF112 Adaptor Kit

The Belimo ZG-LF112 is a specialized LF crankarm adaptor kit engineered to facilitate the mechanical linkage of LF series spring-return actuators to damper shafts via a crankarm arrangement. This HVAC actuator accessory is critical for field retrofits and custom valve or damper applications where direct coupling is not feasible. The kit converts the actuator’s rotary motion into a linear or offset drive, allowing for precise control of damper linkages and mechanical assemblies. Built with high-grade galvanized steel, the ZG-112 adaptation kit ensures rigid torque transmission without slipping, maintaining air volume accuracy across the stroke. For technicians performing Belimo actuator replacement or damper motor installation, this kit provides the necessary mounting hardware to bridge the gap between legacy hardware and modern LF series actuators. Proper alignment with this HVAC linkage kit reduces lateral load on the actuator bearings, extending the service life of the spring return motor in demanding thermal environments.

• Precise Torque Transfer: Ensures the 35 in-lb torque rating of the LF actuator is fully utilized without mechanical play or hysteresis.
• Universal Compatibility: Facilitates seamless integration between LF series actuators and various third-party damper shafts.
• Durable Construction: Heavy-gauge steel components provide the structural integrity required for high-cycle applications.
• Simplified Field Retrofits: Streamlines the conversion process for older pneumatic or electric systems to modern Belimo electronic control.
• Hardware Included: Includes all necessary brackets, crankarms, and fasteners for a complete mechanical installation.

How does this kit interface with the damper shaft?
The ZG-LF112 provides a crankarm that attaches to the actuator, which then connects to a ball joint and push-rod assembly (sold separately) to drive the crankarm mounted on the damper shaft.

Can I use the ZG-112 with actuators other than the LF series?
This kit is specifically machined for the spline and mounting pattern of the Belimo LF series. Using it with non-LF actuators will result in improper fitment and potential mechanical failure.

Is this suitable for outdoor installations?
While the components are durable, the overall assembly must be protected within a NEMA-rated enclosure if the installation environment is exposed to direct weather or corrosive elements.
