Modern Radiator Valves

Modern 15mm radiator valves supplied in matching pairs, in chrome, anthracite grey, textured grey, matt black, white, white and chrome, brushed brass and brushed nickel. Clean cylindrical bodies and low-profile heads designed to disappear under a designer radiator rather than announce themselves.

Valves are sold in pairs because a radiator needs two: one to control the flow and one lockshield to balance the return. What decides which pair you buy is the pipe geometry — angled for pipes coming out of the wall, straight for pipes coming up from the floor into the side, corner for pipes from the floor turning into the back.

Choosing valve shape

• Angled — pipework comes out of the wall and turns down into the radiator.
• Straight — pipework comes up from the floor in line with the valve.
• Corner — pipework comes up from the floor and turns back into the radiator tails.
• All are 15mm, the UK standard for domestic copper pipework.
• Match the valve finish to the radiator, not to the taps — they sit together visually.

Also in this range: all radiator valves, thermostatic valves, angled valves and straight valves.

Frequently asked questions

What is the difference between a manual valve and a TRV?

A manual valve is a tap — you set the flow by hand and it stays there. A thermostatic valve (TRV) senses room temperature and throttles the flow to hold it, so the radiator backs off once the room is warm. Most rooms benefit from a TRV; the room with your main thermostat should keep manual valves.

Do I need angled, straight or corner valves?

It depends entirely on where your pipes arrive. Pipes out of the wall need angled; pipes up from the floor in line with the tails need straight; pipes up from the floor behind the radiator need corner. Look at the existing valves before ordering.
