fire sprinkler system pressure reducing valve

Pressure reducing hose valves and floor control valves are used to control the pressure of flowing water in standpipe and sprinkler systems. NFPA requires pressure reducing valves where the inlet pressure exceeds 175 PSI. These pressure reducing valves are of the factory set variety. This means an engineer or contractor would fill out a data

Part three in our video series on fire suppression systems examines pressure reducing valves (PRVs). Viewers will learn why PRVs are required in some standpipe systems and how they function to

9/11 · Check valves are a common (but not universal) feature of fire sprinkler risers. They prevent the contents of a sprinkler system—from the riser and connected piping—from flowing out of sprinkler pipes and into the municipal water supply, water tanks, or another source. In wet-pipe systems, they also prevent a loss of pressure downstream.

8/15 · Also note that NFPA 25 requires an annual inspection of “hose connection pressure regulating devices” and “hose rack pressure-reducing devices” (valves; 13.5.2.1, 13.5.3.1), but this only applies if a sprinkler system is part of a combination sprinkler/standpipe.

In fire protection service, pressure reducing valves (PRV's) can be found on standpipes and automatic sprinkler systems in high-rise buildings, in pump houses, on public and private gravity water systems and other situations where conditions warrant their use. The most common application of PRV's is in combined standpipe/sprinkler system
