One of the features that has led to the popularity of ductile iron manhole valves is the possibility of installing a net under the air holes of these manhole valves. To prevent cockroaches from leaving the sewage environment. With all these features, we can say that ductile iron manhole valves are a good choice for special environments.
production of cast iron manhole in Karaj
The cast iron manhole valve is a cover and interface piece from outside to inside the manhole or sewer, which is used as a cover (to visit, cover and prevent people and objects from falling). Generally, these valves are made of materials Gray cast iron or ductile cast iron are produced. Due to its strength and reasonable price, the valve with cast iron material has long been the focus of many projects (communications, water and sewage, gas, etc.).
Manhol Valve Types
Manhole valves have different types in terms of size, construction material, etc. The most common classification of manhole valves is based on their type, for example, cast iron valve.
Manhole valves have different characteristics in each type, for example, the weight bearing and resistance of the manhole valve is different in each type. The difference in the material of the manhole valve is even effective in their pricing. In the following, we will introduce some common and widely used types of manhole valves.
Concrete Manhole Valve
One of the oldest types of manhole valves is the concrete manhole valve. This valve is made using concrete and has relatively high resistance.
Concrete manhole valves are resistant to heat and impact and have a long lifespan, but they do not have good tensile strength. In addition, the price of this type of manhole valve is lower than other manhole valves. These valves are easily designed, manufactured, installed and implemented, and after being placed at the entrance of the well, they create a uniform surface. and over time, they get broken and crushed, so they have given their place to the cast iron valve
cast iron
The most widely used type of manhole valve is cast iron valve. This valve is among relatively heavy valves that cannot be moved easily. The cast iron manhole valve can be recycled, and in case of damage or breakage, they can be melted and used again during the production of a new cast iron valve.

Cast iron manhole valve can be recycled, and in case of damage or breakage, they can be melted and used again during the production of a new cast iron valve. Rust is less common. In addition, the efficiency of the manhole valve (cast iron valve) is more than other valves due to the appropriate weight. The cast iron manhole valve is not so heavy that it is impossible to remove them, nor is it so light that it is lifted when cars pass by.
Also, due to the increase in the price of metals, cast iron valves have attracted the attention of thieves, and we witness the theft of cast iron valves every day, so they are welcomed as an anti-theft type of cast iron valves.

use of manhole valve (cast iron) and where to use
As mentioned, manhole valves of any kind are used to cover the entrance of wells in passages, one of the most widely used of which is the cast iron valve. The benefits and applications of using cast iron manhole valve are many, the most important of which are:
✔️covering the opening of manhole and wells in order to pass through them more easily
✔️resistant and suitable material
✔️ Preventing rain from falling on the underground connections and causing problems such as their decay
At the city level
✔️ used as the main gate of all kinds of facilities and...
The Benefits of Cast Iron Manhole Valve
As said, the application and benefits of using the cast iron manhole valve are many. In the previous section, we examined some of the applications of this valve, and here we intend to introduce some of the advantages of the cast iron valve, which are: uniform for passages and no bumps
✔️ suitable weight and relatively easy portability
✔️ resistance to impact, heat and sunlight
✔️ high safety during installation
✔️ performance Convenient
✔️ Ability to install a valve to turn into an anti-theft valve
✔️ Ability to engrave a logo, logo or number on them, etc.
What is the Anti -theft Manhole Valve?
One of the important problems of manhole valves, especially cast iron valves, is the possibility of their theft. Except for concrete valves that have a high weight and cannot be recycled, other valves face the possibility of theft; For this reason, during their installation, a special lock or valve guard is used to reduce the possibility of theft.
By buying manhole valves and using them at the entrance of wells, the safety of the passages can be increased. The only thing that should be taken into account when buying this product is its resistance, efficiency and cost-effectiveness in terms of usage.
