Its vital to understand the design difference between the umbrella term of pressure regulatingwhich covers all things that reduce, regulate, controll, or restrict water pressureand the more specifically defined terms of restricting and reducing that delineate residual (flowing) and static (non-flowing) reductions. Swing check valve. They are angle hose valves with preset orifices which restrict the volume of water and thereby lower the pressure of the flowing water. All Rights Reserved. The current edition of NFPA 14 requires the following: By definition, the only pressure regulating device capable of regulating both static and residual pressure is a pressure reducing valve (PRV). Z3000 Pressure-Tru Pressure Reducing Fire Hose Valve - YouTube Pressure Reducing Valves - Croker Pressure Reducing Valves Webinar Standpipe Quiz Infographics Videos About Standpipe Fire Hose Stations Standpipe fire hose stations provide quick response during the first few minutes. For these combined riser systems, larger flows are required for hose valves, while sprinkler systems are often required to be tested at minimum sprinkler flow (this could be 14.8 gpm, or lower depending on the hazard). NFPA 13 clearly allows the use of a 2 hose connection on a sprinkler system-only design, but that hose connection is not required to meet the fire service pressure provision and should not be consider for structural firefightingonly mop-up. Angle Hose Valves | American Fire Supply This is a significant consideration, as field-adjustable set pressures may be able to be increased with specific tools and knowledge, while factory-set cannot. Our products and our company have the certificates ISO 9001, TS EN 671-1, TS EN 671-2 and CE, which emphasize that safety is our main concern. Used with a fire hose rack assembly or as a fire dept. This continues in 13.5.3, with requirements for hose rack assembly pressure regulating devicesonce again, using regulating instead of restricting. Although the misuse of regulating devices unintentionally still covers the required maintenance for all devices designed for the purpose of reducing, regulating, controlling, or restricting water pressure, it should be addressed by the NFPA 25 committee.
