looks like a check valve and a vacuum relief is in place (which makes it all better )

Check the manifold construction. No tee fittings are used, Thinwall copper tubing is brazed into a single assembly.

Excellent example of plumbers being sent out to do a man's job.

No plumbers were harmed in the fabrication of that mess - off-season shovel-monkey hours were utilized in the brazing of class M copper tubing into manifolds and fittings

I have seen plumbers do that on 2" copper for large boiler manifolds.

How did they know to prepare for a three valve manifold sometime in the summer?

Is the main copper also, or is it galvanized?

all-copper construction - it was a sales pitch that they would use "commercial" valves and fittings, showing off a brass valve and such. Since I never saw any fittings (except the male adapters) on their manifolds, I can only assume they made manifolds in large enough quantities that there was always something in stock for whatever number of zones an install had.
