My pool is built in such a way that the filter is located below the waterline. When I blow out the line and close the valve at winter closing. The valve leaks over the course of the winter and as a result it cracks the valve as the water seeks its own level. I noticed the plastic ball valves fail and cause me issues. I am considering a brass valve for the deep end and was wondering what the water chemistry would have on valve. Would Chlorine destroy the valve. Any suggestions on how to fix permanently.

At the Refinery we used "Double Block and Bleed". Two closed valves a small distance apart with an open valve or plug between them. Sounds extreme for a pool but it is just 2 more valves and 2 bleeder valves or plugs. Point bleeder down if you can -horizontal section. And you can use plastic.$$

Or disconnect the pipe and cap off?

There are ball valves with bleeder valves to remove the remainder of the water in the valve, just unscrew the bleeder valve.
