  • RA-FN category image

    RA-FN

    The RA-FN valve bodies are used in two-pipe heating systems.
    The valves are manufactured from brass with nickel plating. The pressure pin of the gland seal is of chromium steel and works in a lifetime lubricated O-ring seal. The complete gland assembly can be replaced without draining down the system.

    The valves are supplied with a grey protective cap, which can be used for manual regulation during the construction phase. The protective cap must not be used as a manual shut off device. A special manual shut off device (code no. 013G3300) should be used.

    Compression fittings for 15 mm, 10 mm or 8 mm copper tube are available for RA-FN with 3/8” and 1/2” connections.
    In order to avoid deposition and corrosion, the composition of the hot water must be in accordance with the VDI 2035 guideline (Verein Deutscher Ingenieure).

    It is recommended that formulations containing mineral oil are avoided.
    All RA-FN valve bodies can be used together with all types of thermostatic elements in the Danfoss RA series.

    RA2000

    RA2000 thermostats are gas filled with a reaction time of only 10 min - the fastest in the world for mechanical thermostats. The snap-lock makes installation easy and requires no use of tools.RA 2000 thermostats regulate the flow of hot water or low-pressure steam through free-standing radiators, baseboards, or convectors in hot water and two-pipe steam systems.
