Kartell K-Therm Straight Thermostatic Radiator Valve - Chrome

The straight-pattern version of the K-Therm Refined TRV, for radiators where the pipework runs horizontally out of the wall rather than up from the floor. Construction and finish match the angled variant — brass body, gloss chrome, vertical thermostatic head — giving a consistent look across a project where both pipework configurations are present.

Specifications

For Trade & Installers

Straight-pattern body suits wall-run pipework where flow and return enter the radiator horizontally. R½" BSP connections are standard across UK panel radiator valves. Brass construction compatible with open-vented and sealed systems. At 108.5mm overall height, the head sits lower than the angled equivalent (127mm) — useful to note in tighter installations.

For Homeowners & Carers

This valve connects to the radiator from the side rather than from below, making it the right choice when your pipes come out of the wall horizontally. It controls the heat output of a single radiator, letting you set different temperatures room by room. Fitting requires a qualified plumber.
