Would that be on your Suprima boiler?
Control logic, tells it to open/close, how it goes about it depends on the boiler,
That's about all you need to know

Well to be fair with the Suprima there is a little more to it.
Control logic tells it to open.
The gas valves internal design protocol (obviously created by a woman) then feeds back a big F-you and kicks the PCB square in the electronic nuts and refuses to do anything on general principle .
Hence when you need a new PCB, odds are even the gas valve is locked into a buckaroo mode and will need changing as well.

No, the question is not specific to my Suprima boiler 
, which for those with suspicious minds is now working wonderfully well just like mr Potterton wanted.
My question is nothing more than curiosity because I know how zone valves and many more bits work but have no idea about a gas valve

Which gas valve? Asking 'how does a gas valve work' is a bit like asking 'how does an aeroplane work' - they might all look quite similar from the outside and achieve a similar end result, but the way they go about it is different according to which one you pick
Many different types of gas valves..........I remember in the old days of pilot lights, a thermocouple sitting above it would get hot and produce a voltage that I guess would open the gas solenoid. I presume those days have gone.
Out of interest then, how does a gas valve work on a WB condensing combi?

a WB condensing combi will have an air gas ratio gas valve and what the gas valve does is controlled by electronic monitoring of what the boiler is doing the boiler internally will decide how much gas the boiler requires you cant control anything on this boiler except critical values which we wont advise you about on here
