How do I disconnect a steam radiator?

My home is heated using (Circa 1930) Steam heat and I need to do tile work behind my kitchen radiator. It has one (apparently functioning) shut off valve, and I’d like to disconnect the radiator temporarily and then reattach when the remodeling job is complete.

Can I shut down the radiator, disconnect and still allow the furnace to operate during the remodeling job?

thanks in advance,

If your radiators operate by steam and are not on a loop system, ( meaning that a loop system radiator would have an inlet pipe on the left and an outlet pipe on the right feeding the next radiator down the line.)
You can safely detach your radiator after fully closing the valve. Disconnect the slip nut counterclockwise with a 16"-18" pipe wrench. Have plenty of rags at the ready to
catch the condensed water from within when you detatch it. As a safeguard, the boiler should not be running when you detach the radiator just in case the valve does not fully seat, you wont get burned by flowing steam. You can safely operate your system
indefinitely with a radiator detatched.
