VHX Valve Sets with RAX Thermostatic Sensor for Designer Radiators & Bathroom Towel Rails

Application

VHX floor 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 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 un- der-neath the towel rail, parallel with the wall.

VHX wall connection

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

▪two different surfaces matching most radiators

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.
