With the hose attached to the fire hydrant, the valve can be opened to provide a powerful flow of water to extinguish a fire.
Fire hydrant valves provides access to water supply for the purpose of fighting fires. The water supply may be pressurized or unpressurized. Every hydrant has one or more outlet to which a hose may be connected.
Most fire hydrant valves are not designed to throttle the water flow; they are designed to be operated full-on or full-off. The arrangement of most dry-barrel hydrants is for the drain valve to be open at anything other than full operation. Usage at partial-opening can consequently result in considerable flow directly into the soil surrounding the hydrant, which, over time, can cause severe scouring. Where a hose has a closed nozzle valve, or connects to a fire truck or closed gate valve, one must always attach the hose to the hydrant before opening the hydrant's main valve.
There’s 5 different types of valves to choose from, see their specifications:
