Identifying some Redblock EGR Components

I'm doing some EGR research.

Can someone ID these two EGR components at the bottom?

And as a bonus, what EGR cars might they be found on?

Thanks, Dave B

Those look like Pulsair components to me. Not directly EGR-related by function but many(all(?) redblocks, some whiteblocks) cars have EGR if there is Pulsair.

Good job. Thanks. That pointed me in the right direction.

#1 is a solenoid valve made by Pierburg. I haven't identified that specific one, but it's definitely NLA. Nearly identical valves have been used by Volvo from numerous cars up to current models for air injection, boost control and charcoal canister purge.

#2 is PN 3507160, and as you said, related to Pulsair. It too is NLA.

Do you need one? I think I have 2 used valves out in my shop.

No I don't need it. Just research so far for some vacuum diagram work for my page and this stuff recently came up.
