Radiator Valves

I am working on a quote for a customer.  Currently a two-pipe steam system.  This customer like a lot of control of his radiators and is constantly adjusting the radiator valves.  What are some good options to quote to help him out.  Some valves are stuck in place after having been shut off for many years (kids moved away and the bedrooms haven't been used since).

All considerations welcome.

    More Information

    What type of 2-pipe system.  Are the valves original?  Some had orifices in them or were modulated open - closed with a 1/2 turn or less.   Many old valves can be made to operate like new with servicing and in many cases will work better.  Just need more information.

    Wish I knew

    Being that I am much of a steam novice, I couldn't tell you what it has for valves!  The majority have a round handle that seems to screw in multiple revolutions.  A couple appear to have been replaced and have a handle and what probably used to be a dial setting.  Hope this helps.

    A thousand words

    Post a picture of the valves so the system can be identified. Some of these systems worked on ounces of pressure and had special proprietary air venting/vacuum features. They were the Cadillac of systems, and can still work great.

    It may be difficult to give a quote on all the necessary work, until you are into the job, so maybe time and materials would be more realistic.nbc
