## Summary description

Uponor Fluvia adapter M30 x M28 is a mechanical connection adapter designed to mate telestat actuators with compatible radiator valve stems. It provides a secure M30 to M28 thread interface for mounting thermostatic or motorized actuators, ensuring correct alignment and reliable actuation. Suitable for retrofit or new installations where a thread size conversion is required.

## Long description

Uponor Fluvia adapter M30 x M28 is a mechanical connection adapter that provides a secure threaded interface between telestat actuators and radiator valve stems with different thread sizes. Designed for straightforward mounting, the adapter converts an M30 actuator thread to an M28 valve spindle, enabling correct alignment and reliable transmission of motion from thermostatic or motorized actuators to the valve. The adapter is suitable for retrofit work as well as new installations where a thread size conversion is required.
Advantages
The adapter offers a precise fit and stable connection that reduces play between actuator and valve stem, helping to maintain consistent valve travel and accurate temperature control. Its simple mechanical design allows fast installation without special tools and minimizes the risk of cross-threading. The robust construction ensures long-term mechanical reliability in domestic and light-commercial heating systems.
Suitable for
Connecting telestat actuators with M30 thread to radiator valves with M28 spindles
Retrofit projects where actuator and valve thread sizes differ
New installations requiring compatibility between actuator models and existing valve bodies
Residential and small commercial hydronic radiator systems
Key specifications
Thread conversion: M30 to M28 mechanical adapter
Application: connection between actuator and radiator valve spindle
Compatibility: designed for telestat-type actuator interfaces and standard M28 valve stems
Construction: durable mechanical coupling suitable for repeated actuator changes
Use environment: indoor hydronic heating systems, radiator valves
How to use
Fit the adapter onto the radiator valve spindle by engaging the M28 side first, then screw the telestat actuator onto the M30 side until hand-tight. Ensure correct axial alignment so the actuator stem engages the valve spindle without offset. Check for smooth operation by actuating the valve through its full travel and reconfirm that there is no lateral play. If necessary, tighten to the manufacturer’s recommended torque while avoiding over-tightening that could damage threads.
Usage recommendations
Before installation, verify that the actuator model and valve stem dimensions match the adapter’s M30-to-M28 conversion. For best results, inspect threads for damage or contamination and replace the adapter if wear or deformation is present. Use with compatible thermostatic or motorized telestat actuators and follow local safety and installation guidelines.
