Radiator steam vent brand recommendations
So, I'm looking to replace my 1 pipe steam vent valves on all my radiators this year. Two years ago when I moved into the house I replaced and balanced my system using Gorton valves on the radiators, and a big mouth vent on my main. The system itself is balanced quiet well right now, all the radiators heat up within about a 5min or so variance. The problem I've had with the Gorton valves since almost day one is that once all the radiators have heated up and the valves close, two or sometimes three of them will still make a sputtering sound or a high pitched whistling. They are generally always the same radiators. I have tried to clean them and I checked my steam pressure setting to make sure the cut in and cut out wasn't too high. I even had an older steam guy come by and look at it and make sure it's working correctly while he was cleaning the boiler. Everything seemed to be good according to him.
But anyway... my main question is does anyone have recommendations on a decent brand for these vents?
I know this can be like asking different car mechanics what brand oil they prefer haha.
Would I just be better off sticking with Gorton valves since I already know what numbers I'll need or would another brand be better?
Thanks for your time and help all!
