Windsor One-Pipe Steam TRV

Many steam radiators are too big, meaning that when the heat goes on in winter, your home becomes a sauna and you can’t do much about it. Our new Windsor One-Pipe Steam TRV offers a solution that’s quick to install and better looking than you might think.

A steam TRV lets you dial down the heat with localized temperature control on each radiator. Installation is a ten-minute job and there’s no need to disconnect any part of your heating system.

Our Windsor One-Pipe Steam TRV has a built-in vacuum breaker and is supplied with a Maid-O-Mist air vent for quicker, easier installation. Standard ⅛” NPT thread makes it a very straightforward to retrofit to your existing one-pipe steam radiators.

It’s time to ditch chunky, white plastic screw handles. Instead choose from four exquisite finishes to suit your interior and make a perfect match with our Windsor control valves and Whitworth wall stays.

Our new steam TRVs are compatible with any one-pipe steam radiator – the oldest, the newest, the freshly restored, the gracefully aged.
