    This problem that you're having isn't uncommon. My company actually struggles with this same situation and have for over a couple years now. The only fix that we've come up with, which you've already mentioned, is to print the sheets using raster. Sure the file size is significantly larger and when you zoom in on the sheets the quality isn't nearly as nice but it's more important to get the intent across and have it look correct on sheets.

    I was just about to put a new thread on this. It's still an issue in 2017.2. No known workarounds?

    Ultimately, if you can see what it is does it really matter?
    Using a filter for all pipe accessories (Which overrides the system settings) to make them black and solid line irrespective of the system line colour helps.
    You could also try shared symbols in your families. Shared families are unaffected by system settings

    I've gotten this to work. What I did was create a Generic Annotation Family of the 2D "bowtie" symbol, with Masking Regions in the two triangle areas. I then brought that GA family into my Valve family, and set the Valve's 3D geometry to only be visible at Fine Detail. The "bowtie" symbol is set to be visible at Coarse and Medium, but NOT Fine. The masking region isn't masking the valve, it's masking any overlapping pipes entering into the symbols "zone." Having reducers right up on your valve body will also cause this.

    In my case, I had the opposite problem of OP, when in single-line mode, for the larger valves, the pipes were stopping before they intersected with my bowtie symbol. My workaround was to add short line segments to each side of the bowtie symbol.

    This "Nested 2D family + Detail Level management" trick is how all of our Piping Accessory and Fitting families work for Single Line drawings.
