    Hi,
    I have seen Treated Fresh Air Air Handling Unit fitted with 3 way modulating valve.
    Is it ok?

    Do you mean 3way valves on the coils?

    If so, it deends on what type of system you've got on it.

    Variable flow or constant flow!

    Re: AHU 3 port valves

    The valve is controlled by the leaving air temperature and it is keeping it constant by mixing the incoming water with the outgoing water
