How do I remove this steam convector valve?

[Henri232]

This steam valve on a convector is not closing when pressurized and needs to be replaced. The problem is it is in a very tight spot and I cannot figure out how to remove it. Any help is much appreciated.

Looks like you need to remove some wall.

The convector has TWO unions one is on the supply valve and the other is usually a union ell.

If you loosen both unions (with system off and cool) the element can be removed air vent replaced and element cleaned to give better heat transfer

The "wall" is actually the metal frame the convector fits into
