These Maesta Matte Black Traditional TRV Corner Radiator Valves are designed for homeowners seeking elegant temperature control for their classic radiators and heated towel rails. The key benefit is reduced energy consumption and lower bills through real-time heat output adjustment, with a caveat that installation requires specific orientation for the TRV head and lockshield. They offer a timeless aesthetic with a solid brass construction and a hand-finished wood handle, providing precise room-by-room climate settings.

A TRV allows you to control the temperature of individual radiators by adjusting the hot water flow into them. This helps maintain a consistent room temperature and saves energy by preventing overheating.
For optimal performance, the TRV thermostatic head must be installed on the flow pipe (where hot water enters the radiator) and the lockshield valve on the return pipe (where water exits). Incorrect orientation will prevent accurate temperature sensing and control.
The frost protection setting, typically marked with a snowflake or star symbol, allows a small amount of water to circulate when the ambient temperature drops below approximately 7°C. This prevents the radiator and pipework from freezing and potentially bursting.
The temperature is set by turning the numbered dial on the TRV head. Higher numbers correspond to higher room temperatures. Consult the user manual for specific temperature equivalents for each setting.
These valves are designed to be compatible with most standard water radiators and heated towel rails that have 1/2" BSPT radiator connections. They feature 15mm compression fittings for connecting to your pipework.
Wipe the wooden handle gently with a soft, damp cloth. Avoid using harsh chemicals or soaking the wood, as this can damage the finish.
The box contains a complete set, including the Thermostatic Valve (TRV), the Lockshield Valve, and a User/Install Manual.
Ensure the TRV head is not set to its minimum or frost protection setting. Check that the TRV pin is not stuck; it should move freely when pressed. Verify the lockshield valve is not fully closed.
Adjust the TRV head to the desired temperature setting. If the room consistently deviates from the set temperature, check for drafts or heat sources affecting the TRV sensor. Ensure correct TRV and lockshield orientation.
Check all compression fittings and the radiator coupler for tightness. If leaking from the valve body, ensure the valve is correctly seated and seals are intact. Turn off water supply and re-seat or replace valve if necessary.
Carefully remove the TRV head (usually unscrews or has a retaining nut). Inspect the connection and reattach securely, or replace the TRV head if damaged.
