Valves are materials that are installed at the ends of water pipes and are responsible for interrupting and connecting the flow of water and adjusting the flow rate and the combination of hot and cold water.


The valves are a set of breakers that are installed at the ends of water pipes, which interact with the flow of water and regulate the intensity of the flow and the combination of hot and cold water. In general, lions are divided into two types of health and industrial, which is described here.


In addition to disassembling the flow of water and adjusting the flow and composition of hot and cold water together, the use of other sanitary valves is beautifully and in the interior, which has become the first priority today, and the next is saving water consumption.

Definition of component: Gates are usually integrated in the factory and sold, so it can be considered as a building component.
Technical Specifications: Generally, the valves are made of two kinds of rice alloys or dry lead, and their only coatings are those that create distinctive viscosities. Of these two sexes, rice is better than drought lead. Because lead is corrosion after some time, and in addition, it will be harmful for health reasons. For this reason, these types of valves are not standardized and not sanitary. In accordance with standards 6679 and 1546, all metal parts used in the manufacture of sanitary valves (except for handles) should be of rice alloys. However, the parts in contact with water should not be made of brass alloys with more than 2.5% lead. Types of coatings that are more suitable for valves include rice, bronze, copper and steel, among which if the stainless steel is original, it is better than other products. It also has better resistance to decay, and feels less water spots due to its appearance, and is more appropriate in terms of beauty. Other bursts, like bronze or copper, are only bronze and copper plating, and they are mostly diversified, and may be due to the yellow or red color they have nostalgic sensation to buyers.
All materials used in the manufacture of sanitary hoses that are in contact with water should be sexually selected, resistant to water up to 90 ° C and resistant to the environment, and not corroded when used for any other parts used in milk. It should also not be toxic and should not cause any changes in the quality of appearance, color, smell and taste of drinking water consumed. Meanwhile, it should not lead to the growth of bacteria and endangers human health.

Chromium-bound outer surfaces and chromium-nickel coatings must comply with the requirements of Standards 2-2 and 6-2 of the Standard No. 6679. After the metal used in the valves, plating is of great importance, which can have a significant effect on the resistance of the valve, and the better the plating quality, the lateral valves become worn out. For example, if the milk is 25 micron and the coating is real, it will have a very long life-span. The minimum thickness for nickel is 10 microns and chromium is 3.0 microns. In the case of hot water mixes on the left and cold water on the right.

Various types of valves include simple, classic, lever, pedal, ocular (automatic) valves.

In the past, only lacquers have been available in the market, but now they can be seen in a variety of models and colors, now available in a wide variety of valves in four groups: washers, pedals, levers, and electronic eyes that are known as ophthalmic eyes. Rice alloy is more expensive than lead, and offending producers use lead as much as possible to reduce their production costs.

Simple valves: Milk is only installed to control the flow of water and does not perform the mixing of hot and cold water, such as mixed blends. These lions have the following components, which are similar to most other valves.

- body

- Disc: In tap and taper valves, the same ball or cylindrical cone.

- Seat: where the disk is located, or the body and disk interface or the washer. It is often made of softness to make sealing work.

- Category and field: A flange or handle is connected to a disk. It usually closes or closes by tilting the valve socket.

Pedal Gates: The best choice for public places is pedal or non-pedal valves due to the lack of energy needed, such as electricity and batteries, as compared to electronic valves. But they also encounter problems when using it. In the new pedal gears, features such as adjusting the amount and temperature of hot and cold water and the retractable pedal are considered for ease of cleaning and added to the benefits. These lions can be used in places like schools, hospitals, all medical centers, hotels, mosques, restaurants, and more. Other advantages of the pedal and ocular types are the lack of contact with the milk, which prevents the transmission of infectious and dermatological infectious diseases, and reduces the amount of water consumed and even energy as a result of the cutoff rate. Hence, public places are the best choice.

Lever valves: Lever valves are divided into two standing and wall models, the standing type is usually used in a washbasin and a sink, and the wall type is used in the bathroom and toilet. Of course, the wall type is also used in a washbasin and a sink. In a lever valve, a cartridge is used instead of the brain. Cartridges are available in two types of plastic and ceramic, the ceramic type is better and the product of European countries, especially Spain and Italy is more desirable. Their plastic type uses plastic rings o in the form of a cylindrical cartridge to control the flow of water. Some lions and armchairs also have LED lights that have a decorative aspect. In this type of valve, according to the temperature of the water, the LED lights change, and these lights energize themselves from the pressure
