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.

Max. work. pressure: 10 bar, max. diff. pressure2): 0,6 bar, test pressure 16 bar, max. flow temp.: 120 °C
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.

Danfoss pre-settable valve assemblies incorporate easy setting adjustment with clearly engraved setting markers scaled from 1 - 7 and N.
Setting values can be set quickly and precisely,
without the need for tools, as follows:
Remove protective cap or sensor.
▪
Turn red ring to the desired setting value.
▪
The preset level can be selected in 0.5 increments
between 1 and 7 (see chart for flow rates). At setting N the valve is fully open (flushing option).
