Is there any H2S in the injection water? The combination of H2S and chloride (Cl-) can limit your CRA acceptable options. As mentioned by other the dissolved oxygen level also plays a critical role in the selection.

Let me make my case more clear.
I want to use one Launcher for 2 lines. Then I need a device to guide the pig to each of the lines.
For my client, shutoff is important; but if these wye piece cannot provide shutoff, then I should add another isolation valve as well.
Do you have any solution?
For an offshore project we have plenty of pig receiver and launchers (totally 13 EA) and we are doing some optimization to reduce the QTY of the launchers and receivers because of the space limitations.
I came across to divertible or bi-directional or pig switches and I am curious to know some...
