When to use stainless steel NPT ball valve?

If the corrosion exposure is exterior only, or interior but mild (i.e. treated cooling water), I’d have no problem with the stainless valves- unless it was offshore or immersed etc. and the exterior conditions were severe such that you’re relying entirely on the exterior coatings of the carbon steel for protection.

Can a brass valve be used on a stainless steel line?

As you’ve noted, brass is more of a galvanic risk than stainless is in a galvanic couple with either zinc or steel. As you’ve also noted, a small valve on a large line is OK from an anode/cathode area perspective. The same is true for a stainless flange on a carbon steel line.

Can a stainless steel valve be used in carbon steel piping?

For any service where carbon steel is already a marginal selection from a corrosion resistance perspective, avoid the stainless steel valves.

What do you need to know about brass ball valves?

They have a three-piece bolted body that disassembles inline for access to internal components. Use with water, oil, air, inert gas, and steam. For installation in instrument panels, these valves have threads and a hex nut below the handle.

What kind of fittings do I need for a ball valve?

All are compatible with Swagelok®, Let- Lok, and Parker A-Lok fittings. Use these valves with water, oil, air, inert gas, and steam. Flip the toggle to quickly turn these valves on and off. All have threads and a hex nut below the handle for installation in instrument panels.

When to use stainless steel or carbon steel valve?

For high ionic strength, well oxygenated untreated water, or where the water is hot and contains a lot of chloride, avoid using the stainless steel valves, and consider whether or not carbon steel pipe is the right choice too.
