TRV Valve Kits

Choosing your kit in three steps 

• Decide who controls the temperature, and from where. External adjuster (staff or occupant, outside the casing), remote sensor (head inside, sensing outside) or built-in sensor (everything inside the casing).
•  
• Choose your balancing method. RA-N with a lockshield for conventional balancing; RA-DV Dynamic Valve™ for pressure-independent flow limitation set at the valve.
•  
• Confirm connections and access with our technical team so the kit, radiator and casing arrive as one specification — no retrofit surprises on site.

 External TRV Kits 

•  Replacement range for 9330-41 Standard External TRV Kit

•  
•  For wards, classrooms and communal areas where the temperature needs adjusting without opening the radiator cover. The remote adjuster mounts on the outside of the LST casing and drives the valve inside through a capillary connection, so the adjustment point stays accessible while the valve, pipework and lockshield remain enclosed. 

 Remote Sensor TRV Kits 

•  Replacement range for 7463-41 Internal TRV Kit With Remote Sensor 
  

•  
•  For installations where the thermostatic head sits inside the casing but the temperature must be sensed in the room, not the warm air pocket behind the cover. The remote sensor is mounted outside the enclosure, giving the head an accurate reading of the space it is controlling.

 Standard TRV Kits 

•  Replacement range for 9210-13 Standard Internal TRV Kit 

•  
•  The simplest arrangement: a thermostatic head with built-in sensor fitted directly to the valve inside the radiator casing. Suited to plant-side or commercial installations where the setpoint is fixed at commissioning and occupant adjustment is not required. 
  

Aero RA built-in sensor with RA-DV valve 

 The dynamic balancing upgrade to Kit 5, pairing the same built-in sensor head with an RA-DV Dynamic Valve™ DN15 angle valve body and lockshield. Flow limitation is preset at the valve before the head is fitted and the cover closed. 

 Standard TRV and Lockshield Packs

 For radiators supplied without a Contour casing, or where a conventional 15 mm TRV and lockshield pack is all the schedule calls for. 

RAS-C² Radiator Pack with RA-N valve 

 A standard 15 mm TRV and lockshield pack: Danfoss RAS-C² thermostatic head with built-in sensor, RA-N angle valve body and matching lockshield (Danfoss pack 013G6005).  

RAS-C² Radiator Pack with RA-DV valve 

 The dynamic balancing upgrade to Kit 7, supplied as a 15 mm radiator pack: RAS-C² head, RA-DV Dynamic Valve™ body and RLV-D lockshield (Danfoss pack 013G7662).

For the specifier, that means a balanced system without a separate commissioning schedule, and a flow setting that can be recorded against each radiator on the drawing.

For the estates team, it means fewer cold-radiator callouts when the system changes around it.

Choose the corresponding RA-DV kit to add dynamic balancing to your selected control arrangement.
