4.26 Labels for Sprinkler System Control Valves

Reference: 2022 NFPA 13 Section 16.9.3.5

All sprinkler and standpipe control valves shall be provided with identification signs at each valve to indicate its function and what it controls. Also, sprinkler control valves, including pressure regulating control valves (PRV's), shall be provided with a permanent label/tag that identifies the static pressure and residual pressure at a particular flow that is available at the valve outlet.

Note: All field adjustable pressure regulation valves (PRV's) for sprinkler systems and standpipes, including fire pump suction and discharge PRV's, must have a permanent tag that indicates the setting/pressure setting (i.e.; for standpipe fire hose valves it would be the setting in inches of water and for fire pump PRV's it is the pressure setting).
