Ordering
The VHX-sets are specially designed for towel
rails and designer radiators with '50 mm bottom
connection' and ½” connection to the radiator.
The VHX-sets include a RAX thermostatic sensor
for room temperature regulation.
The sets provides the perfect finishing touch for
towel rails. The aesthetically pleasing and compact design allows the sensor to be mounted under-neath the towel rail, parallel with the wall.

1)
The kv-value indicates the water flow (Q) in m³/h at a pressure drop (Δp) across the valve of 1 bar;
. At setting N 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 of the setting value 1. The
kvs-value states the flow Q at a maximum lift, i.e. at fully open valve at setting N.
2)
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. The differential pressure can be reduced by the use of the Danfoss differential pressure regulators.
