The Maesta Traditional Thermostatic Radiator Valves are ideal for homeowners seeking a sophisticated aesthetic for their designer or cast-iron radiators without sacrificing modern efficiency. These antique brass valves offer precise temperature control to help optimize energy usage and reduce heating bills; however, users must ensure correct orientation during installation, as the thermostatic head and lockshield are not interchangeable.

They are designed to fit most designer and cast-iron style radiators with standard 1/2 inch BSPT connections.
These are mechanical thermostatic valves and do not require electricity to function.
No, these valves must be installed with the thermostatic head on the flow side and the lockshield on the return side.
Yes, avoid harsh chemicals or abrasive sponges. Use a soft cloth and mild soap if necessary to prevent damage to the finish.
The internal mechanism will automatically open slightly if the ambient temperature drops below 7°C to encourage circulation and prevent freezing.
Verify the valve is installed on the correct flow side. If installed backward, the internal thermostat will not function correctly.
This is often caused by water flowing in the wrong direction; ensure the flow and return pipes match the valve locations.
Ensure the radiator has been bled of air and that the central heating pump is operating correctly.
Installation must be performed by a qualified plumber to ensure the system is correctly balanced. The valves utilize 15mm compression fittings for the pipework and a 1/2 inch BSPT connection for the radiator.
Important: These valves are NOT bi-directional. You must install the thermostatic head on the flow pipe and the lockshield on the return pipe. Failure to follow this orientation will result in incorrect operation or noise in the system.
For care, wipe the brass finish with a soft, damp cloth only. Avoid abrasive cleaners or acidic chemicals, which can strip the protective antique coating or lead to tarnishing over time.
