What it is
The ONYX 15 mm angled thermostatic radiator valve (TRV) is supplied as a twin pack for controlling the flow of heating water through individual radiators. The angled body pattern suits pipework that meets the valve at 90 degrees, such as a supply rising from the floor or dropping from the wall. Each valve carries a thermostatic head that regulates flow according to the temperature set on the dial.
Signs this part needs replacing
- Radiator stays cold or heats unevenly with the valve open
- Water weeping from the valve spindle or gland nut
- Head does not respond when the room temperature changes
- Valve body seized and the head cannot be turned
- Radiator cannot be controlled and overheats the room
Before you order
- Confirm the pipework is 15 mm and matches the valve connections
- Check whether an angled pattern suits the pipe run, or whether a straight pattern is needed
- Confirm how many valves are required — a twin pack covers two radiators
- Check the existing system and valve heads for compatibility before swapping
