RAS-D Domestic Radiator Thermostats are manufactured to the highest standards in the most modern computerised plant of its kind, and perform in a way others find difficult to match.

The RAS-D now comes with the revolutionary new Revolver valve. The Revolver addresses all the shortcomings of all manufacturer’s current generation of bi-directional TRVs, incorporating a ‘flow selector’ feature allowing the installer to change the direction of the flow through the valve simply by turning the setting ring through 180°.

The RAS-D also features a unique snaplock method of mounting the sensor onto the valve body, eliminating the need for special tools.

A discreet locking and limiting feature is also incorporated. With built-in sensor models. a convenient 'Positive Off' feature is provided, as well as a 'Frost Protection' setting.

Approved to European Standard EN215, and manufactured under BS5750, EN29002 and IS09002 Quality Systems.
