Control valve for polymer transfer

[Alexander R.]

Is there any control valve that is designed to transfer polymer without or at least with minimal degradation of polymer mixture?
I am thinking mostly for the polymer flooding application in oil industry. Standard control valve would have too high shear forces acting on the fluid mixture which would lead to high degree of mechanical degradation.

Mokveld makes a low shear axial choke valve to reduce emulsification of oil water mixtures. You can find info here.

I'm sure there are other low shear valves that I am not aware of, but this seems like it may be a situation where you would want a custom vale.

A series of baffles and or reducers may also work for you, but that will depend on the amount of adjustability you are looking for.

Thanks for tips. This technology looks interesting. Will try to find out if it is applicable for polymer transfer as well.
