Pumping Liquids into several Vessels - Best Valves to use?
if you have a reaction which is running automatically (under observation)
and want to drain the liquid from flask 1 through its bottom drain valve into flask 2, flask 3, flask 4...
which 'multi channel' valve would be a proper choice?
flask 1's bottom drain valve > valve with 3 outputs > each vale output is connected to a different flask 2,3,4...
I could find a perfect product yet... found one 5 in 1 valve but its kinda pricey...
anyhow any other solutions?
channel 3 x 3 way valves into the same line?
to get the 3 outputs?
what type of valve to use, there are screw in valves , twisiting valves, twisiting valves with nut,
glass or teflon.
I assume a screw teflon valve is the best choice if you want to turn it with an electric motor.

What is your desired volume and flowrate?
Solenoid valves would be easy to control,
eg https://www.ebay.co.uk/itm/254604782514
Controlling motorised valves is more complex as end-stop controls/sensors are usually required
Peristaltic pumps may also be useful,
even with flasks that do not have a bottom drain valve,
allowing use of cheaper rbfs.

I use gas washer heads, tubes and hand primer pump to suction liquids out. They work with any vessel that has a matching ground joint.

What sort of chemicals are you working with? Something like a custom PTFE valve is going to be $$$. If you can get away with stainless steel and
solenoids or hand valves, just make a manifold. https://www.pneumadyne.com/images/categories/F_PM_AL_10.jpg Reaction flask drains into the end and out of each of the manifold holes.
