Danfoss RAS-D2 Domestic Radiator Thermostats

Introduction

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 bidirectional 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 settings to connect the valve to the pipe work. The valve bodies are reversible and bidirectional 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. The temperature range is from 8°C to 28°C.

Quality
All Danfoss RAS-D2 sensors and RA-FS valves are manufactured to the highest standards in factories assessed and certified by BSI against ISO 9001 / BS 5750.

Design
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
