The valve needs a correct size allen wrench pushed down onto the valve pin into the socket. if you look into the top of the valve you can see that it is machined for a allen wrench.( 10mm from memory ) It will undo anti clockwise without the need for heat. You can then remove the valve unit and will be able to see the seal. There is only 1 to replace.
Have you tried doing a Walther CO2 cylinder Mark ?
