Belimo ZDB-LF Angle of Rotation Limiter with End Stop for LF Series Actuators

The Belimo ZDB-LF is a mechanical angle of rotation limiter with an integrated end stop, designed specifically as an accessory for Belimo LF Series direct-coupled damper actuators. This precision-engineered accessory allows HVAC technicians and controls engineers to mechanically restrict the actuator's range of travel, ensuring the damper operates only within a defined rotational arc.

Key Features:

• Mechanical angle of rotation limiter with positive end stop functionality
• Compatible with Belimo LF Series spring return direct-coupled actuators
• Allows physical restriction of actuator rotation range for precise damper positioning
• Prevents over-travel and protects damper blade and linkage components
• Simple, tool-minimal installation directly onto the LF actuator
• Manufactured by Belimo to exact tolerances for consistent, repeatable performance

The ZDB-LF is an essential accessory for applications where the full 95° stroke of the LF actuator is not desired or where the damper must be mechanically limited to a specific range of travel. It is listed as an approved accessory across the full Belimo LF Series product line, including the LF24, LF24-S, LF120, LF230, and related LF variants used in commercial and industrial HVAC systems.
