• Four Complete Valve Sets: 4 x thermostatic radiator valves and 4 x matching lockshield valves, enough to fit four radiators from a single order
• Automatic Room Control: The liquid-filled sensor opens and closes the valve as the room warms and cools, helping prevent overheating and wasted energy
• Balanced Heating: Each lockshield regulates the return flow so every radiator heats evenly, avoiding hot and cold spots across the house
• Fits Standard 15mm Pipework: Angled pattern for standard 15mm UK central heating pipework, compatible with most existing radiators and boilers
• Matching White Finish: The same white heads and bodies on every radiator for a consistent look in each room of the house
• Several Rooms In One Box: Fit four radiators at once, ideal when upgrading bedrooms, living areas and hallways at the same time

The LavaTherm 4 Pack contains four complete radiator valve sets in a white finish, each made up of one thermostatic radiator valve (TRV) and one matching lockshield valve, for standard 15mm UK central heating systems. It is the easy way to upgrade several radiators in one go.

Each TRV has a liquid-filled sensor that opens and closes the valve automatically as the room temperature changes, so every room can be set to its own comfortable level. That helps prevent overheating and reduces wasted energy compared with manual valves.

Every radiator needs two valves. The lockshield sits on the other side of the radiator and regulates the return flow, so the system can be balanced and each radiator heats evenly without hot or cold spots.

The angled pattern suits standard 15mm pipework and fits most existing radiators and boilers, making it ideal for replacing older valves or fitting out a new installation. Brass bodies give a durable fit on every radiator.

In the box: 4 x thermostatic radiator valve, 4 x lockshield valve.
