What are the advantages and disadvantages of gate valves and full-bore
Ball valves for mains water, and isolating parts of a CH system.

A ball valve is to set the level of water in a header tank, a gate valve
is use to shut off or allow a flow of water.

Two completely different uses.

Not quite. There is such a thing as a lever ball valve and it is a good
choice instead of a gate valve

Ball type float valves are deprecated technology

So what is the alternative to control the level in a water tank?
