Types of valves in fire line video
@hsetrainer1593 Жыл бұрын
There are four main types of valves on a fire hydrant - the gate, butterfly, check and plug valves. These hydrant valves are at the bottom of fire hydrants, and their job is to open and close the plug that allows water to flow. These types used for fire hydrant include: Dry-Barrel Hydrants, Wet-Barrel Hydrants, Warm-Climate Hydrants, and Flush Hydrants.
