Sunrad valve type

I have never installed one of these, are angle valves or the straight type preferred for single-pipe steam.

    Whatever will provide the most room for fast steam and slow water to travel in opposite directions at the same time. A full-port ball valve would work if it's rated for steam (SWP = more PSI than that radiator will ever see). It doesn't need to throttle; just open and close.

    Thanks, never thought of using a ball valve for steam.
    They make convector shutoff valves. Very useful for sunrad. Female by female angle.
