Gate valves vs. Ball valves.

To answer the OP, although others will know more...ball valves (in this
context) give full flow, as do gate valves. Only ball valves give no
flow; gate valves (a) leak a bit and (b) tend to jam. They're also much
slower to operate.
IME neither gives full flow.
Ball valves can leak too.
