The new RAS-D2 radiator thermostats are the latest addition to the Danfoss TRV range. They are designed for use in 2-pipe domestic heating systems like designer radiators or towel rails.
All RAS-D2 Combi Packs comprise of a RA-FS bi-directional valve and a RAS-D2 sensor. Combi packs are also available with a RLV-D lockshield valve.
The valves have a ½” BSP (R½”) tail piece connection to the radiator and include 8mm, 10mm and 15mm compression fittings to connect the valve to the pipe work.
The valve bodies are reversible and bi-directional and include a flow-selectable feature to ensure trouble free installation without any risk of water hammer.
The valve is supplied with a protective cap, which can be used for manual regulation during the construction phase. The cap must not be used as a manual shut off device. RAS-D2 sensors incorporate a “Frost Protection” setting and a “Positive Off” feature for maximum user flexibility.
Temperature range is from 8°C to 28°C.
All Danfoss RAS-D2 sensors and RA-FS valves are manufactured to the highest standards.
All Danfoss radiator thermostats and valves are manufactured in factories, assessed and certified by BSI against ISO 9001 / BS 5750.
Valve bodies are manufactured from brass with chrome plating. The spindle in the gland seal is made of chrominium steel and works in a lifetime lubricated O-ring. The complete gland assembly can be replaced without draining down the system. |

- Matching valve body, fully interchangeable with radiator thermostat valve bodies
- Available in 15mm & 8/10mm with compression fittings
- Available in 15mm version with 10mm push-fit elbow
- Available as separates or in convenient packs with radiator thermostats
The RLV-D range of domestic lockshield valves are identical in finish and dimensions to the
RA-FS valve bodies used with the RAS-D2 and RAS-C2 radiator thermostat combi packs. All of the fittings, including the tailpieces, are fully interchangeable for total ease of installation.
Available in angled pattern 15mm and 8/10mm sizes with conventional compression fittings and in a version incorporating a 10mm push-fit elbow, the valves are ideal for new build, repairs and system upgrades.
Adjustment of the lockshield valve is by means of a 6mm Allen key. The setting cover is nickel-plated brass, which is screwed onto the valve body.
An accessory pack which converts the valve into a conventional wheelhead valve is also available.
The valves can be purchased separately or in easy to buy combi packs, which include a lockshield and wheelhead valve. Versions are also available with RAS-C2 or RAS-D2 sensors, please refer to the Product Selection Guide for more details. |
