Gating Down Pressure Reducing Valves
Flowing water from standpipes in high-rise buildings during fire operations is as old as time. For many decades the standard operating procedure included a firefighter opening the nozzle bale fully and a second control firefighter gating down any excessive pressure, by using the handwheel on the standard hose valve. This technique allows the nozzle firefighter to properly apply the desired spray pattern, while delivering the optimum pressure/flow pattern and avoids the bad practice of gating the nozzle down by the bale. Gating the nozzle will provide an ineffective nozzle flow pattern and reduce the proper application of water on fire. This technique must be practiced and coordinated between the nozzle firefighter and the control firefighter for a successful operation.
