The Plumbright Angled Thermostatic Radiator Valve (TRV) and Lockshield set is designed for homeowners looking to upgrade their heating system with precise, room-by-room temperature control. Its primary benefit is the 6-level wax-filled sensor that enables efficient energy usage by allowing you to dial in the exact comfort level for each space. While the grey finish offers a modern, high-end aesthetic, users should ensure they have a standard 15mm pipe system, as this set is not compatible with smaller or larger diameter configurations without adapters.

Yes, the product is sold as a complete set containing both the thermostatic radiator valve and the matching lockshield.
Yes, provided the towel radiator uses 15mm piping and the valve orientation is compatible with your pipe entry point.
The finish is a contemporary grey designed to complement modern decor, typically featuring a smooth, semi-matte coating.
Frost protection is typically active on the lowest setting (often marked with a snowflake symbol) of the 6-level dial.
You will need a pair of adjustable spanners or a pipe wrench, a pipe cutter or hacksaw, and potentially some PTFE tape for the threads.
The valve is designed for angled mounting, but the internal mechanism is universal for standard 15mm domestic radiators.
Check if the internal pin is stuck due to inactivity. Remove the sensor head and gently press the pin in to ensure it springs back out.
Ensure the pipe is cut square and the compression nut is tightened correctly. If it persists, check that the olive is properly seated.
This may indicate an incorrectly balanced system. Adjust the lockshield valve on the other side of the radiator to regulate flow.
To install this set, ensure your heating system is drained before removing existing valves. The 15mm compression nuts and olives require a tight, firm grip with a wrench to create a watertight seal; avoid overtightening as this can crack the compression olive. For maintenance, periodically wipe the exterior with a damp cloth to keep the grey finish clean. Do not use abrasive cleaning agents as they may scratch the surface. Ensure the sensor head is not obstructed by heavy curtains or furniture, as this will prevent it from correctly reading the room temperature.
