Niva One-Pipe Steam TRV


Our thermostatic valves add localized temperature control to stop you from sweltering.

Keep the winter air outside and save the AC for summer. Niva Steam TRV enables thermostatic control for one-pipe steam radiators and installation takes just five minutes.

Self-regulating sensors inside the valve automatically turn off the radiator when the room is a little too hot, and turn it back on again when the room cools, maintaining a comfortable ambient temperature.

What’s more, thermostatic valves save money and reduce carbon emissions. No heating system is complete without them.
