The G-Rad Straight TRV Thermostatic Radiator Valve and Lockshield set is designed for homeowners and heating installers seeking an aesthetic and functional upgrade to their central heating system. This set provides precise, individual temperature control for radiators while enhancing the room's appearance with a polished copper finish; however, it is strictly intended for 15mm pipe systems, which may require adapters for older, non-standard plumbing setups.

No, this set is designed specifically for 15mm pipework.
Installation involves draining the heating system. If you are not comfortable with plumbing, we recommend hiring a professional heating engineer.
The finish is high quality, but it is a decorative coating. Regular cleaning with a dry cloth will help maintain its appearance.
The lockshield is used to balance the heating system by controlling the return flow of water, ensuring all radiators heat up at the same rate.
Yes, the head can typically be removed for maintenance or replacement, provided it is compatible with the G-Rad valve body.
Check if the internal pin is stuck due to inactivity; remove the head and gently depress the pin to ensure it moves freely.
Ensure that the compression nut is tightened correctly and that the olive is seated properly on the pipe.
Use the lockshield valve to balance the system by restricting flow to radiators closer to the boiler.
To install this set, ensure your system is drained of water before beginning. The valves are compatible with standard 15mm copper or plastic pipework; ensure you use compatible inserts if using plastic piping. Once installed, tighten all connections using a suitable spanner, but avoid overtightening the brass components to prevent damage to the threads. To maintain the polished copper appearance, wipe the valves down with a soft, dry microfiber cloth. Avoid using harsh chemical cleaners or abrasive scouring pads, as these will strip the finish and lead to oxidation over time.
