What is the building valves?
Building valves are metal devices that are used to open and close the flow of liquids and gases. In general, valves are classified into two categories: domestic and industrial valves. .
Today's modern faucets are not only a great tool for easier use of water, but by using them, you can optimize the use of water and try to solve the problem of water shortage in the world.

Types of Models Models available in the Market
Sanitary faucets generally have two main parts: inner shell and outer cover.
Manufacturers often use brass alloy or dry lead for the inner part.
Of course, nowadays many In order to comply with health issues, manufacturers no longer use dry lead and use more brass alloy.
If lead is used, if the plating of the milk is not done well, it will dissolve in water over time and It will cause dangerous pollution for people.
Knowing the types of construction faucets, one can choose a better option during renovation or when the faucets need to be replaced due to reasons such as decay.
Valves are generally classified into two categories: valves with gaskets and without gaskets.
Ball valves, disc valves and cartridge valves are known as valves without gaskets, and pressure valves are considered as valves with gaskets.< /p>
Hub valves
Building ball valves, which are also called single-lever valves, are often used in kitchens. >
The valve lever in this type of valve actually controls the metal or plastic ball inside the valve body.
One of the disadvantages of construction ball valves is that compared to other valves without washers and due to the number of parts used in the valve, there is more problem of dripping.
Discus valves
The new generation of luxury and modern construction faucets are ceramic sanitary faucets.
Ceramic sanitary faucets are also known as single-lever faucets, whose lever is placed on a wide cylindrical body.
>
In disk faucets, hot and cold water are mixed together inside a tank, which is called pressure balance cartridge tank.
Two ceramic discs are placed at the end of this tank, which move They control the water pressure up and down. To adjust the water temperature, the lever is designed to rotate to the right and left. The disc valves are of high quality and compared to others. Construction faucets have better performance and as a result, they will need less repairs.
Cartridge valves
One of the types of two-lever construction valves are cartridge valves, which have an appearance similar to two-lever pressure valves. The only difference between these construction valves is that cartridge valves are without gaskets, but pressure valves have gaskets. Although these two types of valves are similar in design, the difference in their performance can be easily noticed. Pressure valves require applying pressure on a washer when turning the lever. .
The outflow of water from pressure building valves is not as easy as cartridge valves. In cartridge faucets, the smallest turn of the lever enables the water flow to be turned off and on.
Compressive valves
One of the oldest construction valves are pressure valves, which are mostly seen in old buildings.
Although they need to apply more pressure to turn off and on the water flow, but compared to other types of faucets, they have better performance and less dripping problems.
The act of mixing hot and cold water. Pressure valves are operated using two levers.
