Reference to Sections - 7.1.1.2 , 7.1.1.2.1 , FIGURE A.7.3.1(a) & (b) of  NFPA 24 regarding 'a valve shall be installed on each hydrant'.
Reader understand that "Hydrants" referred in NFPA 24  are basically  Dry hydrants or hydrants in freezing area. Hence a valve  is required (SHALL) to  be installed  on a hydrant connection to the main with self draining facility. 
However, if the hydrants are wet barrel type , in  non freezing area and Independent  valves ( 65mm)  are installed as per Section - 7.1.1.4 at the hose outlets then the above referred control valve ( on Section 7.1.1.2 ) is it required?
 
Even though individual hydrant maintenance is possible by installing the above valve, more valves in a system means more chances of leaks, maintenance issues and is not cost effective in a system contains over 100 hydrants.
