Yes this maybe true but needle valves also have different types of tips. Tbh everything should be globe valve or butterfly. Except the withdrawal valve than angular plug type needle
The thing with regulating flow with ball valves it creates a non uniform wear on your valve. That’s why they are recommended for only shut off/on
It’s not the valves I feel is the need for compression but the easy alignment with tubing. Tbh sanitary tri clover valves is more ideal from the columns than use compression tubing adapters and unions to create the pathway.
