The pintle is just coated like all the rest. A solid SS pintle can't be pushed or pulled with a electomagnet which is what a solenoid valve is. Although I would not run sw through any solenoid most of them are fine for rodi pre and post. I just compared a new one to one that is now 10 years old and can't tell the difference. Absolutely no wear what so ever.
