Radiator Valves open and close during heating cycle
Kevin_25
Member Posts: 5
I have replaced all main and radiator valves over the past 3 months in a one pipe steam system but during the heating cycle the valves close and then open to let a burst of steam out and close again within seconds. I have verified my pressuretrol has a cut-in 0.5 and differential of 1 but I never notice any reading on the pressure gauge on the bottom of the pigtail. The pigtail and gauge were both replaced this fall, could they be clogged already? I do drain out the returns weekly. I have also noticed that valves which have replaced have bocome fowled. Help! I'm getting tired of being woken up each morning by the clicking and hissing.

quality of water
Water runs clean in seconds from the return pipes. Gauge glass is clear.0 -
An oversized boiler
can cause this. Check the Net rating of your boiler against the actual amount of radiation. For radiator ratings, get Dan's book "E.D.R.". If you have anyhting that's not in there, post again and we'll see what we can do.
