I am looking for a company that sales a rough in valve with 9" on center not 8" on center? Anyone no any manufacturers of the bathtub valves & faucet that will match this criteria?

If it is for a deck mount faucet the majority of 8" rough faucets are expandable. moen would be a good choice because you can solder ridgid copper between them. i personally have only seen 4" and 8" and 12" wall mount tub faucets.
