I’ve run into a problem: for needle valves used in highly saline environments, what material should be used? 316L？ Titanium steel? The bore of the needle valve is not large; is it feasible to use an electric actuator for control?

There are needle valves made of PTFE; they have good corrosion resistance, but they cannot handle high pressures
