Whether you’re looking for TRV or manual radiator valves, we have a broad range of styles and designs available for both radiators and towel rails. Valves don’t have to be purely functional, and selecting the right one can really accent the look of your radiator.
Use our BTU calculator to easily work out what size radiator you will need, by entering information about your room in our calculator.
A valve is a simple tap that regulates the flow of hot water in and out of the radiator which then changes the temperature of the room.
There are two types of valves: non-thermostatic (manual) and thermostatic (TRV).
The TRV controls the radiator's temperature by sensing the room air temperature and automatically opening and closing the flow to the radiator to maintain a preset temperature.
A manual valve maintains the temperature of the radiator regardless of how warm the room is.
On a radiator there are two types of valves which work as a pair, the wheelhead for the water inlet (also known as the flow) and the lockshield for the outlet (return).
The wheelhead valve is the temperature control; the lockshield valve is used to balance the radiators in the system so that they all heat up at roughly the same rate. Simply put, the radiator closest to the boiler if left unchecked would heat quicker than the one sited at the other end of the house, so the lockshield valves should be set opened at increasing amounts the further away from the boiler the radiator is.
The thermostatic valve allows you to automatically regulate the flow of hot water into the radiator. The control inside the valve head will increase or decrease the flow of hot water to the radiator depending on the ambient room temperature. This allows you to set the valve to stay open until the temperature you want to reach is achieved. If the temperature then drops the valve will reopen.
A manual valve maintains the temperature of the radiator regardless of how warm the room is. The control of the radiator temperature can be adjusted by hand by turning the valve either up or down.
