These Maesta Traditional Manual Angled Radiator Valves are designed for homeowners seeking an elegant and functional solution for traditional heating systems, especially those with classic heated towel rails or radiators. The key benefit is their timeless aesthetic, crafted from solid brass with a hand-finished wood handle, which adds a touch of luxury and complements period-style interiors. A key consideration is that these valves are manual and not bi-directional, requiring specific installation orientation for optimal performance and frost protection.

No, these are manual radiator valves, meaning they require manual adjustment to control the water flow and regulate temperature. They are not automatic thermostatic valves.
The lockshield valve is used to balance the heating system by setting a fixed opening on the return pipe. It is typically adjusted once during system setup and then left in place.
Install the manual valve on the flow pipe and the lockshield valve on the return pipe. Ensure 15mm compression fittings are used for pipework and the 1/2 BSPT coupler connects to the radiator. Always consult the user manual for detailed instructions.
It means the valve has a specific flow direction. The thermostatic head must be on the incoming hot water pipe (flow), and the lockshield on the outgoing pipe (return) for proper function.
The frost protection automatically allows a small amount of water to flow when the ambient temperature drops below approximately 7°C, preventing the radiator and pipes from freezing.
The valves feature a solid brass body with a hand-finished wood handle. The finish is antique brass with a matte coating.
For instructions on fully shutting off the valve, please consult the online user manual provided with the product.
Ensure the valve is installed correctly with the manual (TRV) head on the flow pipe and the lockshield on the return pipe. Manual valves require physical adjustment to change temperature settings.
Check that the manual valve is turned to allow water flow. Ensure the central heating system is operational. Verify that the lockshield valve is not fully closed.
Check all compression fittings and the radiator coupler for tightness. Ensure pipework is clean and free of debris before connection. If the leak persists, contact a qualified plumber.
Frost protection activates below 7°C. Ensure the valve is correctly oriented and that there are no blockages preventing water flow. Verify the ambient temperature is indeed below 7°C.
Setup: These radiator valves are designed for angled installations. It is crucial to install the thermostatic (manual) valve on the *flow* side of the heating system and the lockshield valve on the *return* side. This orientation is important for correct operation and the effectiveness of the frost protection feature. Ensure compression inlets are connected to 15mm pipework and the radiator coupler (1/2" BSPT) is securely fitted.
Compatibility: Compatible with traditional radiators and heated towel rails, particularly those in period-style or heritage homes. They connect to 15mm compression pipework.
Care: To maintain the antique brass finish, clean the valves with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals, as these can damage the finish. The wood handle should also be wiped with a damp cloth and dried immediately. For detailed instructions on fully shutting off the valve, please refer to the online user manual.
