re: Noisy control /valve assembly
We have recently installed a large number "Moteur electrothermique ABNM" http://fr.cd.danfoss.com/xxTypex/199791_MNU17410363_SIT32.html
They seem to be working well but for one thing. They cause the valves they are attached to to vibrate LOUDLY from slow clicks to buzzing.
Can you suggest some solutions. One forum suggest many solutions, but we would like one coming from you. Perhaps the pressure is too high in the boiler? What would be the correct range?(this is a 3 story school).
Any ideas would be welcome.
