Data sheet X-tra™ Collection Valves for Jaga
Application
The new X-tra Collection is a TRV specially designed for towel rails and designer radiators. Its new
and innovative self-sealing ½" valve to radiator
connection makes for a seemless, elegant and
easy installation.
The towel rails valve set includes a matching lockshield valve with drain-off function. The valves
and sensors are available in Chrome and Inox.
The valve set 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,
avoiding the risk of accidentally knocking the
sensor.
Small to medium-sized convectors with valves
matching in colour or in contrast colours, is also
an interesting application for this series of valves.

Max. working pressure: 10 bar, Max. differential pressure²⁾: 0,6 bar, Test pressure 16 bar, Max. flow temperature: 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; kv = Q: √Δp.
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.
