1 "ball valve - features and specifications

When replacing radiators, installing a plumbing or heating system, installing gas meters, etc., you will definitely need to purchase a ball valve. But before you make a purchase, you must decide on the main technical characteristics of the device. Below we take a closer look at what an inch ball valve, its features and the most important characteristics.

Device

Ball valve is a valve that can be used in various types of pipelines. Its locking mechanism is designed as a ball with a through hole.

To open the passage, the ball should be turned so that the hole is parallel to the pipeline. If you turn it 90 degrees, i.e. perpendicular to the body, the passage will be blocked. In this case, the tightness of the mechanism is ensured by two elastic rings that fit snugly to the ball.

As a rule, the control of the locking mechanism is carried out by hand with a lever, which is connected to the ball with a rod. True, there are inch valves, which are controlled by an electric drive. They are used in systems of automatic overlapping of the water supply.

Due to the simple design of the locking mechanism, the device is characterized by reliability and durability. However, it cannot be used to adjust the flow, i.e. fittings are intended only for complete overlapping or opening of the flow.

Specifications

The main characteristics of the product include the following parameters:

• Dimensions of ball valves in inches and mm - refers to the diameter of the inlet and outlet pipe;
• The material from which the product is made;
• Conditions under which valves may operate.

Below we take a closer look at all these parameters of the product in question.

Dimensions

First of all, it must be said that the diameter of the ball valves is indicated in pipe inches. One pipe inch is equal to the outer diameter - 33.5 mm. Often, pipe inches are indicated in fractions, for example, sometimes a 3–8 inch ball valve (three eighths) can be found, which equals the outer diameter - 17 mm.

Since the tube inch differs from the traditional one (25.4 mm), and is also tied to the conditional passage, and not to the outer diameter, it is better to use special tables to obtain accurate data. This also applies to reverse conversion, for example, a ball valve 32 in inches is 1?. With independent calculations, you can easily get confused and make a mistake.

Note! When choosing a product, you should pay attention not only to its diameter, but also the method of installation. There are valves with both internal and external threads, as well as for flange connection of pipes (large diameter).

It should be noted that the size of a 1 ”ball valve is rarely found in pipelines. More often, such valves are mounted on the container, screwing it to the fittings. However, on sale you can find an inch valve for both water and gas pipelines.

In domestic pipelines, however, you can most often find a 2-inch ball valve,?,?, 3 ’, etc.

Materials

An important parameter of any ball valve is the material from which it is made, since the cost of the product and its durability depend on it.

Most often inch valves can be found made of the following materials:

• Brass and other copper alloys - products of this type are the most expensive and at the same time the most durable. This is largely due to the fact that scale does not settle on the brass.

• Stainless steel - these valves are usually used in high pressure pipelines or during transportation of hot liquid. The disadvantage of stainless steel is that it accumulates scale more strongly, which shortens the life of the product.

Note! On sale you can find low-quality valves made of silumin. You should not acquire them, as they very quickly fail. Silumin products can be determined by lighter weight and the fact that their price is much lower than for counterparts from higher quality materials.

Working conditions

The characteristics of ball valves must necessarily meet the conditions in which it is planned to operate. As an example, we give the characteristics of a brass inch valve:

As a rule, these specifications contain instructions that are included with each tap.

Note! For the gas pipeline it is strictly forbidden to use water taps, as they are less tight, however, you can use a gas valve for the water supply.

Here, perhaps, is all the information you need to know in order to purchase suitable and high-quality inch ball valves.

Conclusion

Ball valve is a reliable valves, which is widely used in household communications. The only thing that during the installation process is not to encounter problems, and the device worked reliably, when choosing, it is necessary to choose the right diameter and take into account its main characteristics.
