Gate or Ball valve?
 

If I want to use a valve specifically for flow/rate control...and not so much for on/off...is a gate valve a much better choice than a ball valve?

Yes, gate. There's another one that is supposed to be even better for flow control and cost about 4 times more but I forget the name of it. Once I remember I'll post it.

Yes gate valve is alot better for flow control then a ball valve. adjusting ball valves is a pain!!

Globe valve. :)

I was assuming you were looking at larger valves like 1/2" + for water.

Yup, that's it Gary.

Yes, I'm planning out the plumbing and realized that some of the valves I was planning were for shutoff and some were more for control.

I was just reading about globe valves...sounds like they will interfere with the current a bit more than a gate valve would.

Yes, most of the plumbing is 1", 1.5", and 2".

Thanks, it sounds like I'll be using more gate valves than I first thought.

or a knife valve, you just pull/push on the handle to adjust flow.

Wow...I just added it up and I'm over $700 worth of valves and bulkheads and I haven't even factored in pipe! What a great way to spend money!

Different than a gate valve? Or just another name that some refer to it as?
