Help sought on removal of scubapro inflation and auto dump valve

I have a scubapro neoprene drysuit but the inflation value is stiff and is a
little slow to close when I release the button which lets more air into the
suit than I want. I've decided to replace the valves but would like some
advice on how to remove them so that I don't do any damage to the suit. Is
it a simple case of grabbing the front and back and using force to unscrew
them or is there a special tool/technique to undo them both? Thanks for your
help,
John

I am not familiar with this valve in particular, but all the others I have
come across are removed as you describe. Once off, it should be possible to
dismantle the valve by removing the circlip from the valve stem. If the
O-rings are OK just clean and grease the stem. It could save you the cost of
a new valve.

Had another go but it didn't budge, it's definitely on tighter than hand
tight
On the underside of the valves it says "IS Tech AB". Do these guys do things
different?

If the valve is faulty, what have you got to lose by putting some force into
it? (Someone may have applied silicone sealant to the threads and/or gasket
to cure a leak.) Get brutal with it.

or perhaps... Si Tech ;)

They're stiff, but do-able.... sometimes you can wedge a screwdriver across
the back to add leverage...
