I believe the valves you removed are the
air release valves. Removing them is not
a good idea. They are made to vent the air
that is being created by the boiler as the
steam rises. As they heat up they close down
and allow the steam to heat the radiator.
By removing them the total system will be
out of kilter.
Any plumbing supply will have new ones, even
home depot.
I would put new ones in all over, and opperate
the system. Make sure the site glass has a
water mark of 4/5 up the top.
Like mine you may have a set back electronic
thermostat that is not made for steam use.
It tends to short cycle and not really get
the radiators hot.
I set the thermometer 6 or 7 degrees up
and make the boiler run for 1- 1 1/2 hours.
This causes all the radiators work well.
If new vents do not work out well call a
service tech to inspect the system. Which
is probably something that should be done
yearly.
