The Stirling Bold Thermostatic Radiator Valve (TRV) & Lockshield kit is an ideal choice for homeowners looking to upgrade their heating system with both precise temperature control and a premium polished brass finish. It is perfectly suited for those aiming to improve energy efficiency while adding a sophisticated, lacquered aesthetic to their radiator setup. While it offers excellent performance, please note that it is designed specifically for 15mm pipework, so users should verify their system dimensions before installation to ensure compatibility.

It is compatible with all radiators using standard 1/2 inch BSP fittings and 15mm copper piping.
While it is a standard installation, it requires draining your heating system. If you are not confident with plumbing, it is best to consult a professional.
The finish is lacquered, so a soft, dry cloth is usually sufficient. Avoid metal polishes or abrasive pads.
The lockshield is used to balance the system by limiting the amount of water flowing out of the radiator, ensuring all radiators heat up at a similar rate.
This valve is designed for 15mm pipework. Using it on other pipe sizes would require additional adapters not included in this kit.
The valve pin may be stuck. Remove the thermostatic head and gently press the pin down; it should spring back up on its own.
Ensure that adequate PTFE tape or appropriate jointing compound has been applied to the threads and that the nut is tightened securely.
This often indicates the radiator is improperly balanced. Adjust the lockshield valve to restrict flow slightly.
Installation requires basic plumbing skills, including the ability to isolate your heating system and drain water from the radiator. Ensure you have the correct pipe size (15mm) and that the BSP fittings match your radiator inlet. For maintenance, wipe the valve body regularly with a soft, dry cloth to prevent dust or moisture buildup. Avoid using abrasive chemical cleaners, as these can strip the polished lacquer and lead to premature tarnishing of the brass finish.
