When it comes to LST radiators, one of the most commonly asked questions that we receive is regarding the valve options.

Generally, these questions are what options do we offer for the temperature control and can the service users control the temperature themselves?

Contour has been blogging this week about the valve options available to our customers and the choices that they have when installing their LST radiators.

Contour TRV Kits

Here at Contour, we offer four different TRV kits. These are available for both two pipe and one pipe systems.

Here at the product references for out two pipe systems:


90210-13 Standard Internal TRV Kits

This TRV system is often used in areas where they may only need to be adjusted once a year. This is often in corridors and other communal spaces.

They must only be used in BBOE connections to avoid the thermostatic head from getting false temperature readings.


7463-41 Internal TRV Kit With Remote Sensor

Similar to the 90310-13 kit, this TRV is suitable for spaces where it doesn’t need regular adjustment, but the radiator is connected TBOE meaning the thermostat will be located at the top of casings.

This means that instead of the thermostat reading false temperature readings you would locate the remote sensor at the bottom inlet grill.

If you require the remote sensor to be installed outside of the casing then this is something that we can accommodate. However, in this instance, the capillary is 2meters as standard.

9231-41 Standard External TRV Kit

With this TRV kit, the remotes the thermostat and control are remotely placed outside of the casing. This allowes services users the ability to adjust the temperature of the room themselves.

This option is regularly specified and used in patient bedrooms for long-term hospital accommodation.

9213-63 Anti-Ligature TRV kit With Shroud

Similar to the standard external TRV kit, this option remotes the thermostat and control to the outside of the casings, with the addition of an anti-ligature CNC metal shroud making it far more difficult to attach ligatures.



As standard, all the above kits come with an angle pattern Herz TS-90 Bodie and an angle pattern RL1 Return Valve with ½ inch connections.

If you require a straight pattern or reverse angle, please advise at point of enquiry and our estimating team can amend the kit to suit.

All kits are also compatible with our RotaRad valves when the radiator is connected BBOE, this allows access to behind the radiator for deep cleaning.

For added peace of mind, all of Contour’s TRV sets are covered by a manufacturer’s 5-year product warranty.
