Valves For One-Pipe Steam Radiators

Read about the fundamentals of one-pipe steam heating systems here.

Our Windsor XL series is a technically superior valve that allows steam in and condensate out of a one-pipe steam radiator. 

Niva One-Pipe Steam TRV adds temperature control to maintain a comfortable ambient temperature and reduce heating bills.

Both ranges are available in three finishes: Satin Nickel, Natural Brass and Chrome. 

We recommend 1″ valves for radiators up to 5000 BTUs and 1.25″ valves above that. Niva One-Pipe Steam TRVs are rated for use on systems up to 1.5psi. There’s no need for domestic systems to run above that pressure.
