UL 1468-2016 UL Standard for Safety Direct Acting Pressure Reducing and Pressure Restricting Valves (Fifth Edition; Reprint with Revisions Through and Including April 13@ 2018)
These requirements cover direct-acting pressure-reducing and pressure restricting valves intended to reduce the water pressure in standpipe systems or in the supply piping for sprinkler systems. These requirements also cover pressure reducing valves that can be used as an indicating control valve in a sprinkler system. The valves covered by these requirements are intended for use in: a) Standpipe systems installed in accordance with the Standard for Installation of Standpipe and Hose Systems@ NFPA 14; or b) Sprinkler systems installed in accordance with the Standard for Installation of Sprinkler Systems@ NFPA 13. The valves covered by these requirements are intended to be inspected@ tested and maintained in accordance with the Standard for the Inspection@ Testing@ and Maintenance of Water-Based Fire Protection Systems@ NFPA 25. Direct-acting pressure-reducing and pressure restricting valves covered by these requirements include the following patterns and sizes: a) Angle Patterns for Standpipe Use ?C Inlet and outlet openings having nominal diameters of 1@ 1-1/2@ 2-1/2@ or 3 NPS. b) Angle Patterns for Sprinkler Systems ?C Sizes greater than 1 NPS. c) Straightway Pattern for Standpipe Use ?C Inlet and outlet openings having nominal diameters of 1@ 1-1/2@ 2-1/2@ or 3 NPS. d) Straightway Patterns for Sprinkler Systems ?C Sizes greater than 1 NPS.
