Solenoid valves for stock solution control

[harangdos]

Hi!

I need to control a on/off flow of a stock solution with a solenoid valve. The stock A or B will be 100 times concentrated. The question:

Can I use a regular nylon solenoid valve or do I need more expensive materials like brass or stainless steel?

I'm worried about possible corrosion, wear or any chemical reaction.

Nylon is fine, you want to avoided using metals if you can.
