Belimo WTF Linkage

The Belimo WTF Linkage is a specialized mounting kit engineered specifically for the TF actuator series. This heavy-duty linkage is designed to provide a robust mechanical connection between the spring return actuator and B2/B3 ball valve bodies, ensuring precise torque transfer and reliable fail-safe positioning in critical HVAC control systems. Whether you are performing a field retrofit or a new installation, this kit eliminates the guesswork by providing a direct-couple interface that maintains alignment under high-cycle conditions. Using genuine Belimo accessories like the WTF linkage ensures that the stroke and force of the TF24 or TFB series are accurately translated to the valve stem without mechanical play or hysteresis.

For contractors, the Belimo WTF is essential when adapting damper actuators to valves in tight mechanical spaces. It includes all necessary hardware for a valve neck extension, allowing for easier insulation and access to the CCV (Characterized Control Valve) assembly. This linkage is built to withstand the rigorous demands of hydronic heating and cooling applications, maintaining its integrity in both fail-open and fail-closed configurations. By utilizing the WTF linkage kit, technicians can ensure their TF series valve linkage installation meets the manufacturer's performance specifications for long-term operational stability.

• Optimized Compatibility: Purpose-built for TF series actuators and type B2/B3 ball valve bodies to ensure a perfect mechanical match.
• Precision Control: Eliminates mechanical slack, providing accurate seating and opening of Belimo CCV valves.
• Durable Construction: Engineered with high-grade components to handle the constant cycling of commercial HVAC systems.
• Simplified Installation: Standardizes the mounting process, reducing labor time during actuator retrofits.
• System Versatility: Supports both spring return fail-safe actions, ensuring safety in hydronic control loops.

Which actuators are compatible with the WTF linkage?
This linkage is specifically designed for the Belimo TF series (including TFB24, TF120, and TF24-SR) and is not intended for use with LF or NF series actuators.

Does this kit work with standard NPT ball valves?
The Belimo WTF is engineered for Belimo B2 and B3 valve bodies. Using it on non-Belimo valves may result in misalignment and is not recommended.

Can I use the WTF linkage for outdoor installations?
While the hardware is durable, the assembly should be protected by a NEMA-rated enclosure if the TF actuator is exposed to the elements, as the linkage itself does not provide weatherproofing.
