Pressure Reducing Valves thread184-299740 MVPs gfire (Specifier/Regulator) (OP) 27 May 11 12:16 Has anyone dealt with pressure reducing valves? The pressure reducing valve (PRV) is designed to reduce both residual (flowing) and static (non-flowing) water pressure. It must be noted than when hose connections are above the maximum allowed, they may be restricted or reduced to any pressure within the acceptable range within the two design limitation criteria of pre-1993 (100 psi) vs post-1993 (175 psi). Morris Group Online Morris Group University. ..

This design justification was based on fire department hose/nozzle packages dating back to the 1950s and had not yet been adjusted until the 1996 edition of NFPA 14 was released. To understand pressure regulating devices, we first need to understand the difference between the static and residual pressure of water. Made/assembled in the USA or China. Have more questions about pressure regulating devices? Pressure restricting valve. All class I & III standpipe systems to flow a minimum of 500 gpm though the two most remote 2 hose connections (Section 7.10.1.1.1). This section applies to stages but was extracted to NFPA 1s standpipe system chapter, leading to confusion about the standard governing requirements for hose connections. NFPA 13 also allows 2 hose connections for Fire Department Use to be added to sprinkler-only designed systems (8.17.5.2) but does not address any pressure provisions for 2 hose connections. A202.
