Application

Code Nos. and Technical

Data

The integrated high capacity valve, type RA-G 013G8670, is designed for incorporation into convectors from different radiator manufacturers.

All thermostatic sensors in the RA series can be combined with RA-G 013G8670.

Danfoss thermostatic sensors types RA2000, code no. 013G2973 and 013G2974, can be installed directly onto the integrated valve.

For easy identification the protective cap is grey. The valves are nickel plated.

The integrated valves have a reinforced stuffing box to avoid damage on the valve at low temperatures.

The gland seal of the valve can be replaced while the system is in operation.

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).

1)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.

	2) The kv-value indicates the flow volume (Q) in m3/h at a given lift and a pressure drop (p) across the
	valve at 1 bar.	. The kvs-value states the flow Q at a maximum lift, i.e. at fully open valve. If a
	remote temperature adjuster is used, the P-band is increased by a factor of 1.1. If an RTS sensor is
	used, the P-band is increased by a factor of 1.2.
