Reducing the pressure drop across them is one way. Then, what is a valve other than a means of isolation and of dropping pressure/flowrate (rhetorical question)?

Butterfly valves in particular can exhibit this characteristic, and in their particular case, vortex-disturbing "fingers" can be added to the trailing edge of the disc so as to reduce the problem.
