Belimo WLF Linkage

The Belimo WLF Linkage is a professional-grade solution designed to provide a mechanical interface between LF actuator series and B2/B3 series characterized control valves (CCV). Built for high-torque applications where precision is non-negotiable, this hardware kit facilitates seamless power transfer for 2-way and 3-way valve bodies ranging from 1/2" to 3". As a veteran technician knows, the integrity of the linkage ensures that the 35 in-lb torque of a spring-return LF actuator is accurately translated to the valve stem without binding or slippage, protecting the close-off rating of the assembly.

Constructed with durability in mind, the Belimo WLF includes all necessary mounting brackets and hardware to convert a standard damper actuator into a dedicated valve linkage kit. This assembly is optimized for Building Automation Systems (BAS) and commercial HVACR environments where HVAC valve control must remain consistent under high static pressures. Incorporating this LF series actuator linkage into your workflow ensures field-ready reliability and reduces the risk of mechanical failure in critical hot or chilled water loops.

Key Benefits

• Broad Compatibility: Specifically engineered for LF series actuator integration with B2 and B3 flow-control valves.
• Mechanical Precision: Eliminates excessive play in the drive train, ensuring the equal percentage flow characteristic of the valve is maintained.
• Simplified Installation: Standardized mounting footprint allows for quick field assembly, reducing labor hours on actuator valve linkage retrofits.
• Engineered Resistance: High-quality materials resist the corrosive effects of common HVAC media, including glycol solutions up to 60%.

Common Questions

• Can I use this linkage with actuators other than the LF series? No, the Belimo WLF is custom-tapered for the LF series' specific shaft and torque profile; using it with larger series like the AF or smaller TF series is not recommended.
• Does the kit include the valve and actuator? This is the linkage kit only; the LF actuator and CCV valve body must be sourced separately based on your specific Cv and voltage requirements.
• Is the linkage suitable for outdoor installations? While the WLF hardware is robust, if the LF actuator is installed in an outdoor environment, a NEMA-rated weather shield is required to protect the assembly from the elements.
