If your central heating pipes come up from the floor and connect to the underside of your radiator or towel rail, you will need a pair of manual or thermostatic straight radiator valves.
They are most commonly used for heated towel rails or modern column radiators with “underneath” connections. We stock a wide range of cheap straight radiator valves in both manual and thermostatic options. Shop below to find the correct fitting for your floor-mounted pipework.
TAILS THE RETAIL RACCOON SAYS
Straight valves are the right choice when your pipes come up from the floor and connect directly into the bottom of the radiator. For best control, use a TRV on the flow side and a matching lockshield on the return side, then balance the system so all radiators heat evenly. Once you’ve got the right type, match the finish to your radiator for a tidy, joined-up look.
Ideal when the pipes come straight up below the radiator. Straight valves keep the line clean and avoid unnecessary bends.
Great if your existing valves are old, stiff or mismatched. New straight valves can improve control and make the install look sharper.
Perfect if you want a tidy finish with less visual bulk, especially with matching pipe sleeves and floor plates.
If the pipes exit the wall and turn into the radiator, straight valves usually look awkward. Angled valves typically suit that setup better.
Straight valves won’t correct misaligned pipe centres. If the pipework isn’t lined up, you may need pipework adjustment or different valve options.
If the system needs balancing, bleeding, or a clean, changing valves alone may not solve it. Diagnose the cause first for best results.
Straight radiator valves are valves designed for pipework that comes up from the floor and meets the radiator in a straight line. The valve body runs in line with the pipe, making them the neatest option when your radiator connections are directly below the radiator.
Choose straight valves when the pipes rise vertically from the floor and connect into the bottom of the radiator. If the pipework comes out of the wall and needs to turn into the radiator, angled valves are usually the better fit and give a cleaner installation.
Check the valve type and the finish. Decide whether you want a thermostatic valve (TRV) for automatic room temperature control or a manual valve for simple adjustment, then pair it with a matching lockshield for balancing on the return side. Also confirm the thread/connection sizes match your radiator and pipework, and pick a finish that complements the radiator so the install looks intentional.
