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).
Hydrant valves include different parts that include:
1- Cap: The upper cap includes the valve opener, flange and oiled hole located on the upper part of the valve.
2- Body: The body that is placed on the ground includes the watering hole. This opening consists of a cover and a chain and has a flange for safety and connection. The flange prevents damage to the main valve.
3- Middle body: This body is placed underground and consists of a pipe and two normal flanges as well as a safety flange.
4- The lower body: it includes a valve to control the amount of watering and an automatic drain system. It has two flange connections and a receiver opening.

Hydrant valve that can be made screw or flat or lens-like
These valves are made of two types of cast iron or seamless Manisman pipe
In most incidents, the fire hydrant valve is the main method of firefighters to extinguish the fire in the urban area. There are rules and regulations for installing fire hydrants at specific intervals. Also, standing fire hydrants should have free access to buildings, factories, urban and developed areas because these tools are an important part of fire control and security in the discussion of fire extinguishing.
to prevent occasional and occasional use or abuse; Fire hydrant valves need a special tool to open, which is a special wrench at the disposal of firefighters, and it is forbidden to park cars within 3 to 5 meters of the fire hydrant valve, the logic of applying these rules is that in case of emergency The fire hydrant should be visible and within reach of the firefighters.
In rural areas where municipal water systems are not available, dry fire hydrants are used to supply water and also to fight fires. Dry hydrant valve is usually installed by a non-pressurized pipe that has one end below the water level of a lake or pond. It is used by a fire truck pump to suck water from the source.

This type of stand-up fire fighting valves are used in places where there is a possibility of the temperature dropping below zero and the water inside the pipe freezing. The design of this type of valve is done in such a way that the water entering the hydrant and the main valve are installed under the water freezing line.
When the standing fire hydrant or fire hydrant is used, water flows into the main body of the hydrant and the fireman can provide the necessary water to extinguish the fire from the fire hydrant outlets, but when the main valve It closes, the automatic drain valve (Drain Valve) which is installed in the lower part of the pipe opens and as a result it is possible to drain the water inside the main body and the pipe.
Due to the fact that the pipe and the main body of the valve are usually dry and water only flows in it when it is used, it is impossible for it to freeze. This type of hydrants with a dry chamber is also known as “Frost Proof” anti-ice valve.
Usually designed for a working pressure of 250 psi
This type of fire hydrant uses a wet pipe that water always flows into and their upper part is connected inside the ground. The main problem with these fire hydrants is that they don’t have a main valve and they have a separate valve for each outlet.
Standing fire hydrant valve is more firefighting because they use a pipe full of water, they are not used at all in cold areas where there is a possibility of freezing, and they also do not support the shock absorber system against the pipe breaking to prevent water wastage. Therefore, it does not have the advantages of a dry standing fire hydrant.
It is usually designed for a working pressure of 200 psi
