VHX Valve Sets with RTX Temperature Limiter for Designer Radiators & Bathroom Towel Rails
Application
VHX floor connection |
VHX wall connection |
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 RTX temperature limiter for regulation of the return flow temperature.
VHX valves controls the return flow from the radiator and have several features:
▪free choice of left/right mounting direction
▪available in versions for floor or wall connection
▪built-in shut-off function
▪four different surfaces matching most radiators
The VHX sets provides the perfect finishing touch for towel rails. The aesthetically pleasing and compact design allows the sensor to be mounted underneath the towel rail, parallel with the wall.

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

At position 0 the valve is totally closed, i.e. the frost protection is off.
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).
