Side Mount Value Leaking at pressure gauge

I’ve had my Hayward pool about 7 years and the side mount value is not leaking around pressue gauge and I cannot get it to stop.  I’ve decided to just replace it.  I’ve pulled two numbers off of it but can’t seem to find a match.  SP0710X62FV and 21121302005898026.  My sand filter is a S244S.  Can you tell me what model I should be ordering?

The replacement valve would be part number SP0710X62.

The replacement pressure gauge would be part number 4726-0.
