Symmons Valves

Remodeling two bathroms. Both have 23 year old Symmons Temtrol valves.

Should we reuse or is it worth the time and effort to put in a newer valve? Both seem to work fine as the seals have been replaced once already.

I thought the Symmons were warranteed for life.

If we replace what would you recommend.

Thanks
