Leak at multiflow valve

[crawfs2]

I have a leak at the multiflow valve on my sand filter. See photos. Is this an indication of the need to replace the spider gasket?

Do I need a specific spider gasket?

Also - what brand, make and model valve is this?

Re-branded Pentair TA - ?? filter and valve. Not necessarily the spider gasket but the O ring under that lid.

Thanks. Went to local dealer. Long story short. It is a 26 year old aquatec multiflow valve. After attempting to replace the gasket found that the spider gasket was severely deteriorated. Only remedy was replacing the top portion of the valve. Did that and found it leaking from two or three places in the body of the valve. Minor cracks due to age? Went to replace and the valve is a screw in valve. One of the pool supply had any. Time for a new sand filter.
