Built For Bigger Inlets

A 3/4" connection is common on heritage and high output radiators. Choosing valves made for that thread size helps maintain proper system flow and keeps pipework neat. Whether you prefer a thermostatic head for set and forget comfort or a classic wheel/crosshead, you’ll find options that suit period features as well as modern heating systems.

At a glance, what you’ll find in this category:

• TRV and manual pairs tailored to 3/4" connections
• Angled, straight and corner bodies for tidy pipe runs
• Popular finishes such as chrome, brass, nickel, pewter and black nickel
• Heritage details including traditional wheel and crosshead designs
• Options to complement column and cast iron radiators

Pick Your Orientation And Finish

Orientation dictates how your pipework meets the radiator. Angled valves are the go to for most setups with pipes from the floor or wall; straight valves align the pipe and inlet on the same axis; corner valves keep everything close to the wall in tight spaces. 

Once the layout is sorted, match the finish. Select polished chrome for a bright, fresh feel, brushed brass or pewter for a warmer, period style, or black nickel if the goal is a bold contrast. Planning a new room and want to size heat output first?

Fitment, Sizing And Aftercare

Before fitting, check the radiator inlet size and the valve’s flow direction markings. If you’re combining 3/4" radiators with other pipe sizes, your installer may use suitable tails or reducers to achieve a secure seal. After installation, start TRVs at a mid setting and allow a day or two for the room to stabilise, then fine tune. Wipe finishes with a soft cloth and avoid abrasive cleaners to keep surfaces looking new.
