RA-FN/HC:

All RA-FN/HC valve bodies can be used together with all types of thermostatic elements with RA connection. The valve body RA-FN/HC is used in two-pipe heating systems. The valve bodies are supplied with a 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. 013G5002) should be used. To be able to distinguish between other valve bodies of the RA 2000 series the RA-FN/HC protective cap is grey. RA-FN/HC has connection for 12 mm hydro cable both axial and radial compression fittings are available. RA-FN/HC are also available with 1/2” conection. Valve bodies are manufactured from brass with nickel plating. The pressure pin of the gland seal is of chrominium steel and works in a lifetime lubricated O-ring. The complete gland assembly(stuffing box) can be replaced without draining down the system. Should water treatment be used it is essential that dosing instructions of the manufacturer are strictly observed. It is recommended that formulations containing mineral oil are avoided.

RLV-S/HC:

By means of a lockshield valve, type RLV-S/HC, every radiator can be shut off individually to allow trouble-free maintenance or repair without affecting other radiators in the system. RLV-S/HC is intended for mounting on the outlet of the radiator. RLV-S/HC lockshield valves are available in angle version. RLV-S/HC has connection for 12 mm hydro cable both axial and radial compression fittings are available. RLV-S/HC are also available with 1/2” conection.

kvs-value RLV-S/HC 15 = 1.26 m³/h

Factory setting is fully open valve. Dimensions correspond to DIN 3842-1.

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).

Data and Ordering

Close the valve by means of an 8 mm allen key (turn allen key right).

Open RLV-S with 4 turns and the valve will be fully open (turn allen key left).

The kv-value indicates the water flow (Q) in m³/h at a pressure drop (∆p) across the valve of 1 bar;

. The kv-value is stated according to EN 215, at XP = 2K i.e. the valve is closed at 2°C higher room

temperature. At lower settings the XP value is reduced to 0.5K. The kvs-value states the flow Q at a maximum lift, i.e. at fully open valve.

Working pressure = static + differential pressure. The maximum differential pressure specified is the maximum pressure at which the valves give satisfactory regulation. As with any device which imposes a pressure drop in the system, noise may occur under certain flow/pressure conditions. To ensure quiet operation, maximum pressure drop should not exceed 30 to 35 kPa. The differential pressure can be reduced by the use of the Danfoss differential pressure regulators.

Note: The Kvs-value for RLV-S/HC is 1,26m³/h.
