undoing a stuck crossway check valve

[fourboysproduct]

Hi, I have a wall mounted shower bath mixer, I managed to undo the left side check valve with mole grips but the right side even with hammering does not budge. There are two dimples on the cover.Any advice or is there a special spanner required.Thanks

Not sure what you are talking about? Any pics?

Adjustable spanner and pump pliers are up to most tasks.

mole grips will normally just churn anything to pieces

Thanks for getting back,the check valve has smooth round sides so it is getting churned up with the mole grips,
I feel the two dimples/holes must be there for a reason?
