It's a "medium flow" valve which will work- especially since you have the micrometer handle. I'm using one almost identical to this but based on my experience I've been recommending swagelok's "Low flow" valves instead. Reason being that I find the entire useful adjustment range exists in the distance between two tick-marks on the handle. I'd much prefer less sensitivity / more precision. Thus I placed an order for a low flow valve to replace mine. (it's a 12 week lead time while they make a batch so I'm going to be waiting a while for my order.
Your burkert solenoid valve should be good to go. Lots of people around here have had very positive experiences with burkert. It's for a calcium reactor so I'm thinking it may be more precise than I actually need, if that turns out to be the case I may use it on a planted down the road and get a manifold and another needle valve for this setup. Like most of us nothing goes to waste just an excuse for more equipment and another tank.
