More expensive and not available from the sheds..

But well worth it imho. All plumbers merchants carry them, as do
screwfix, toolstation, bes etc.


The gate valve is almost full bore but most "service" valves seem
considerably smaller.

Is there any advantage to using a service valve over a gate valve?

Service valves are smaller in size, and also 1/4 turn. These are both
'advantages', but not huge ones.
