Checking the fire hydrant valve
Fire hydrant valves are usually used in public roads and sidewalks or industrial spaces and yards of sheds and petrochemical oil and gas sites, which are red or yellow in color. These standing street valves are called fire hydrants and their duty These valves are fire extinguishing and water supply to the fire place and control and finally extinguishing the fire.
Street fire hydrant valves are divided into two categories, Dry Hydrant and Wet Hydrant, based on weather zones. We will review and briefly describe both types of fire hydrants.
The fire hydrant basically consists of a flange that is installed on the flange of the main pipe and a vertical standing pipe that is mostly 3-4 inches and sometimes 6 inches and has two left and right T-shaped exits and can also have an exit from the front. And also the head of the hydrant valve which can be made with screws or flat or lens-like (sometimes the head or cap of these valves can have an output flange for installing a monitor as well, which is produced according to the client’s request.)
The materials of these valves are two types of cast iron or seamless Manisman pipe, which can be produced in different classes and courses. The left and right exits are also equipped in the front with special valves or hydrant connections (adaptors).
