Integrated High Capacity Valve, Type RA-G
013G8670

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 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.

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).

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.
