and is based on type of "media" in the tank and tank diameter the valve will be used on. Flow rate "buttons" available for flows between 8 gpm - 25 gpm using this DLFC.
Or in most Cases, you should be able to re-use your existing DLFC, but note if you have the 2850s, it used a "female" 1 1/4" threaded connection, so when replacing an 2850 ( with male thread connection ), you would require a 1 1/4" x 1" bushing and 1" male nipple to attach. Those fittings are sold at most plumbing supply outlets.
