The valves are compatible with standard pipe sizes, and the set includes 8mm reducers for smaller piping requirements.
While simple for experienced DIYers, we recommend a professional heating engineer install them to ensure your heating system remains leak-free and correctly balanced.
The lockshield valve is used to balance the heating system by restricting the flow of water out of the radiator, ensuring an even distribution of heat across all radiators in your home.
These valves are designed for radiators with standard 1/2 inch BSP inlets. Ensure your pipework orientation matches an angled valve profile before purchasing.
Use only a soft, dry cloth for cleaning. Avoid harsh chemicals, abrasive pads, or acidic cleaners.
Ensure the thermostatic head is set to a higher number and check that the valve pin is not stuck by removing the head and gently pressing it.
Check that the connections are sufficiently tightened and that the correct amount of PTFE tape or sealant was used during initial installation.
This often indicates a system flow issue; consider adjusting the lockshield valve to balance the flow through the radiator.
Installation of the Stirling Bold TRV set should be performed by a qualified plumber to ensure system integrity. These valves are compatible with 1/2 inch BSP radiator inlets. The set comes with 8mm reducers, making them suitable for standard 8mm pipework, though they may accommodate 15mm systems depending on the specific setup. For routine care, wipe the silver finish with a soft, dry cloth to prevent water spots or oxidation. Avoid using abrasive chemicals or acidic cleaners, which may degrade the metallic finish over time. Periodically check the valve head to ensure it moves freely, especially at the start of the heating season.
