Stainless steel valves

[Kevin Willis]

Is there any made in the USA. If so , who?

Best I know Manley stuff is USA made,
They make both 2 piece friction welded and 1 piece forged
Highly recommend Forged!!

In your own home state you have Ferrea.

Think I read they weren't anymore or at least some of the cheaper stuff wasn't. I imagine at this point like most co's they bank on their name so some of the lines are outsourced to increase profits. I could be wrong but I don't need to call them at this time to find out and it could change a year from now.

Ferrea is made in Argentina however if you can buy the engine pro valves they are made in the same place I am told.
They are made in Argentina and when compared side by side they are identical.
There is several options for valve quality and the price is attractive compared to similar valves.
if it is an all out deal manley would be my 1st choice> REV also has some nice stuff but not positive where they are made.

Not sure on U.S. ss valve mfgrs anymore because they apparently change sources on a weekly basis, but its worthwhile to try & find out. A great deal of ss is recycled and some foreign metals have only a nodding acquaintance with SAE specs. There are over 100 grades of 'stainless steel'- some of which have so little expensive chromium (which is what defines stainless steel) in them, they will rust. IMHO, if you plan on revving above 5000 rpms, I would NOT personally use welded valves made of anything! A "100% guarantee" seldom includes head & block replacement.

I wasnt sure about manley these days I used to deal with Hank back in '72 (fixed his wifes Pinto Wagon and bought 351 C stuff for our pro stock ) so I called the Tech line and the rep claimed its still USA made

and recommended the forged 1 piece product.

I know for a fact that at least some Manley valves are outsourced. In a particular case, from a worldwide tier 1 supplier, from a Brazilian plant.

My vote is 4 Ferrera they're Hollow stem lightweight stainless series for that class and price you're not going to find better quality

A while back, Ferrea stated their valves were made in USA with USA materials. Not sure if this was their complete line, hard to believe the 5000 series stuff could be US made.

Historically, I am pretty sure all their stuff was from South America. Regardless of the country of origin, we have used quite a few of their higher end stainless valves with very few issues.

Here is a link to where they make the claim of made in USA.

I bought a set of Summit's house brand 2.02"/1.60" valves that are swirl polished and necked down a while back.

Good money and they look great. BUT I don't remember if they are SS or not. I think they are as well as one-piece.

Please look into them.

One-piece exhaust.

I think these are the exhaust valves.

Nickel is the expensive alloying element in stainless: about 4 times the price of chromium.

How many Ferrea valves have broken?

[Newold1]

I would not worry about US made valves today. The US lost that market many years ago. Most good valves today are made in Argentina. Made in the USA is a nice thought but don't expect that moniker to mean what it used to. Sad but true in many industries.

I've been using CV Products X2 when needing steel valves for a few years now. No problems for me very and they're very reasonably priced. I never really thought about it but I just assumed they are made in USA. But looking at the boxes it doesn't say Made in USA anywhere.
