Banging radiator

Hi, 

I’m a contractor doing a kitchen renovation. While working I noticed the radiator above the kitchen is making a lot of noise. Unfortunately I can’t add the video but it’s similar to that of banging pots and pans. 

Now that the kitchen is demoed it’s the best time to fix this issue. I checked the tilt on the radiator and it was dead level; so with shims I put a pitch on the radiator to allow water to drain.  Unfortunately that didn’t fix the issue. 

When the valve to the radiator is closed, no noise. But that could just be because the steam isn’t moving through the line. Do you think it’s a valve issue or a pitch (of the steam pipe) issue?

    The horizontal pipe going to the radiator needs to slope to drain water back towards the boiler. Remodeling may have disturbed the pitch.
    Pictures of the piping?

    Yeah that’s what I’m thinking. Not that I did it; it’s been making noise since they bought the house, but that the pitch is off. Gonna throw a mini level on it tomorrow and if it’s off I’ll correct that. But if it’s pitched properly then the only thing I can think of is the valve. 

    I can post pictures tomorrow but it’s basically what you think it is.
