radiator

Unknown

Every new valves I installed...usa or forgein made, I always take them apart and grease the stem and packing with heat proof grease or "never seize" material.. Go easy on it as you don't want it go inside the system, back to boiler...

best quality radiatior valve

we are interested to learn a high quality straight radiator steam radiator valve. we would prefer American made but wonder if we really getting anything extra for 40 dollars each vs 20 bucks. we are definitely not looking for the ones that get stuck in the close position after a few years as we have very large heavy radiators

valve ?

if it's 1-pipe steam ,the general rule is don't turn it off ;so in that case maybe you could do without a valve-just pipe straight through.--nbc

Quality radiator valves

thats interesting but we are doing some construction that will make a bathroom radiator very hard to ever reach again for repairs.
therefore we want to put a good quality turn off valve on it. that way if there is ever a leak we can turn it off and isolate it and find another way to heat the room. if there is a good quality valve to rely on rather than this chinese stuff, how come it would be real bad to ever have to permanently turn off the radiator as it affects the 1 pipe steam system

steam valve replacement

the theory is with 1-pipe steam valves that if you close the valve some small amount of steam will still get through and then condensate will build up in the radiator robbing the system of its water and maybe triggering a pump to thus overfill the system.
this advice may come from the time when old valves were tired with worn out disks.
if you keep the pressure LOW [below 12oz.] you should have no uncontrollable radiator leaks,so order a good 0-3psi gauge from gaugestore.com and install a vaporstat if you don't already have one.
one reason that people turn off valves is to reduce heat, so a thermostatic vent could solve that problem; however running low steam pressure gets the old system close to its original design specs from the "dead men" who were quite accurate in their radiator sizing.--nbc

Doesn't sound very practical

"doing some construction that will make a bathroom radiator very hard to ever reach again for repairs...... if there is ever a leak we can turn it off and isolate it and find another way to heat the room"

Anything that has moving parts ought to be accessible. Why would you want to make it inaccessible?

closed radiator valve

closed radiator valve

interisting how things come full circle. there is one tenant who turned off a radiator and built a desk around it. it would be near impossible in new york to get non emergency access. now i wonder if that is part of the problem with low pressure and wet steam on the brand new boiler.

there is no pump on this 1 pipe system which has a hartford loop, so does that mean that over filling cant be the problem? is there anything we can do other than get a vapor stat if we cant gain access?-
