Banging pipes

in THE MAIN WALL
Two story rooming house. Each level has six rooms. Each room has a Danfoss RA2000 in line radiator valve with 15 feet of baseboard. The system is a constant circulation with a B+G PL-36 circulator. Automatic air vent in every room. I replaced all the air vents. Every room has heat working but the baseboard bangs in two of the rooms . Any suggestions

    Is there a

    Bypass on the system? How is the boiler piped? Primary secondary? What happens if only one zone calls.

    sounds like....

    Hydraulic jump to me. I would swap out the B&G  for an Alpha 15-58 circ and your problems will disappear. Similar to what can happen to a quick close zone valve w/ a high head circ.

    Primary/Secondary

    It is piped primary/secondary. How about the Taco Bumblebee circulator? .

    Primary Secondary

    So you have two circs, one for the boiler and another for the heating loop.

    Yes

    Yes, Taco 0014 for my boiler loop and B+G  PL-36 for my system.
