Terma - Vario Royal Angled Thermostatic Valve and Lockshield
The ROYAL valve sets from Terma are an Angled set of TRVs (comprising valve and lockshield) supplied complete with a pipe masking set. These are produced in the matching colour to some of Terma's radiators such as the Rolo range.
Angled in orientation which are the best valve choice with side entry radiators where the pipework comes through the floor (For dual fuel, double check with your fitter)
The Vario valves are not bi-directional - so you should fit the TRV head on the flow side.
