These Maesta TRV angled radiator valves are for homeowners seeking to enhance the aesthetic and efficiency of their traditional radiators or heated towel rails. They offer precise temperature control for optimized comfort and significant energy savings by allowing room-by-room heat management. A key consideration is their non-bi-directional design, requiring correct installation on the flow and return pipes.

Thermostatic radiator valves allow you to control the temperature of individual radiators, which helps in optimizing comfort and reducing energy consumption by only heating rooms to the desired temperature.
These valves are designed for traditional radiators and cast iron styles with 15mm pipework and a 1/2 BSPT radiator coupler. They are not suitable for all modern radiator types or underfloor heating systems.
The thermostatic valve (TRV head) must be installed on the flow pipe (where hot water enters the radiator), and the lockshield valve must be installed on the return pipe (where water exits).
The frost protection setting means the valve will automatically allow a small amount of water to flow through the radiator when the ambient temperature drops to around 7°C, preventing the water inside the radiator and pipes from freezing.
Clean the matte black finish and wooden handle using a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could scratch or damage the surface.
The approximate dimensions are 80mm (width) x 55mm (depth) x 143mm (height).
No, these radiator valves are not bi-directional. They must be installed with the thermostatic head on the flow side and the lockshield on the return side for proper function.
Ensure the TRV head is not set to minimum or frost protection. Check that the lockshield valve is fully open. Verify correct installation on flow and return pipes.
Confirm the TRV head is correctly seated and not damaged. Ensure the valve body is not blocked. Check if the lockshield valve is fully closed, which would force water through the TRV.
Gently tighten the compression fittings. If leakage persists, the olives or seals may need replacement. Ensure pipe ends are clean and free from burrs.
Gently try to move the pin inside the TRV head with a non-sharp object (e.g., the handle of a screwdriver). Ensure no debris is obstructing its movement. If it remains stiff, professional inspection may be required.
