BUT,
Alot of members here use needle valves, and for good reason.
Controling the distillate output via RC requires fine movement.

First run last weekend and the Bunnings gate valve must go, not enough control. My question is regarding size for a needle valve. My gate valve says 1/2" on it, which I assume refers to the gate diameter, because the thread appears to be 3/4". Thus, I use a 3/4" Malte to Male When you guys suggest 1/2" needle valves are you referring to the thread size or another dimension (Note: I know little about valves). It would seem that if 1/2" refers to thread size, you must be using some reducers? I'm guess that a 3/4" valve would allow greater flow than a 1/2", but is that problematic?
