Drayton Radiator Valves

Radiator valves control the flow of hot water into your radiator, allowing you to manage the heat in each room. By adjusting a radiator valve set, you can increase or decrease the warmth a radiator emits, helping you save energy and keep your home comfortable.

Different finishes, such as black, chrome or white, give you the option to match the colour of your radiator. At Builder Depot, we stock Eastbrook valves specifically to match the finishes of our central heating and designer radiators.

A standard radiator control valve works like a tap, controlling how much hot water flows through your radiator. When opened fully, more hot water enters, making the radiator hotter. When closed, less water flows, and the radiator cools down.

Options such as a straight, angled, or corner radiator valve are chosen based on the pipework in your room to ensure a neat and secure fit.

A thermostatic radiator valve (TRV valve) automatically regulates the temperature of a room. Inside the valve head is a capsule that expands or contracts depending on the surrounding air temperature.

As the room warms up, the capsule slowly reduces the hot water flow to the radiator, preventing overheating. When the room cools, it allows more water in, keeping temperatures consistent without you needing to adjust the settings. This makes a thermostatic option one of the most efficient radiator valves you can choose.

The right radiator valve depends on your pipework.

• A straight radiator valve is best when pipes come directly up from the floor or straight into the radiator
• An angled radiator valve is used when the pipework comes from the wall or at a right angle to the radiator
• A corner valve gives a flush, modern look where the pipes run neatly into the wall

Valves come in both manual and thermostatic options. With manual radiator valves, you set the temperature by turning the valve, providing a constant heat output. Thermostatic valves self-regulate to keep the overall room temperature at a specific heat level, offering more comfort and reducing the chance of overheating.

Not all radiator valves are the same size. The most common connection in the UK is 15mm, but you can also find 10mm and 22mm valves depending on your pipework. Always measure your pipes before buying a new radiator valve set to ensure compatibility.

On a radiator valve, the numbers (often 0–5) represent temperature settings. A lower number means the valve reduces water flow into the radiator, so it heats up less. On the other hand, a higher number allows more hot water into the radiator, so it emits more heat.
