A bit of history
Centralized water supply was familiar in ancient Egypt, Hellas, and the Roman Empire. Roman aqueducts are still preserved in Italy, Spain and Germany.
Interesting! The aqueduct is the name of the oldest colossal stone structures for supplying water to major cities in Europe, built during the Roman Empire.
Some of them are still used for their intended purpose today. Such a mass of water supplied to the ancient cities had to be controlled. This is how the first samples of shut-off and water-folding fittings appeared. On the island of Capri, archaeologists have discovered ancient brass and bronze cork closures. These are the very first valves in the world, the predecessors of valves, ball and water taps.
The next impetus to the rapid development of gates and valves was the invention of the steam engine. The need for water control and steam control has led to reliable plugs and adjustable spring loaded safety valves.
Some technical solutions have not lost their relevance in our time. In the twentieth century, utilities began to be equipped with butterfly valves, diaphragm valves and ball valves. Today, the development of valves is moving in several main directions:
- durability;
- reliability;
- manufacturability;
- cost reduction.
Ball valve prototypes
The cork crane was known to the ancient Egyptians. Simple and reliable, these devices are still used today. Let's recall the most famous options for their use:
- Samovar. The same one with which tea has always been poured from samovars, both the most ancient and modern electric ones.
- Bath. KrB is still used in the washing departments of public baths, for which it received its official name.
- Gas. Familiar to everyone who uses a gas stove, water heater or natural gas heating boiler.
How a plug valve works
The simplest device is the samovar version. There are two components: a body and a cone - a plug with a rectangular cut and a fixed handle. The body follows the shape of the cork and has the same internal dimensions. By turning the plug by 90 degrees, the slot of the plug is set along the axis of the product, opening the passage for water.The flow is shut off by turning the plug 90 degrees in the opposite direction. The position of the integral handle indicates the position "Open" if it is parallel to the axis of the "spout", and "closed" if the handle becomes perpendicular to the axis of the shut-off valve. In this part, cork and ball devices are very similar. The difference is in the shut-off organ: a cone in a cork, and a sphere in a ball device. The difference is visible when it comes to the seal between the closure and the product body.
To prevent leaks, the plugs made of soft brass or copper were rubbed against the bodies until the gap was completely eliminated by repeated twisting in the fit. Gas and bath models are more complicated, since they work under pressure, and in the case of the gas version, the slightest leak of the working medium will cause an explosion and fire. These models have a closed bottom, a gland with a threaded cover. In ball locks, lapping will not help. Spherical polymer seals are used here.
Who invented the ball valve
Complicated story. There is evidence that the first such device was first used in the fuel lines of airliners somewhere in the middle of the last century.
On a note! According to some sources, a patent for it was issued in 1954 to the American inventor Howard Freeman.
The product did not provide complete tightness and was not widely used in those days. A quantum leap took place later, with the invention of polymeric materials.
The problem was that, unlike the cork, the shut-off element of the new device was a steel ball with a hole in the center. It was difficult to provide a reliable seal between it and the walls of the structure without an elastic and at the same time resistant to abrasion material. The task was brilliantly solved with the advent of Teflon, and later, fluoroplastic. From that moment on, the ball valve quickly conquered the global shut-off valve market. Today, dozens of inventors own patents for various types of such devices.
What are ball valves
Differences in case material
The operating mode and technical characteristics of the working and environment depend on it.
Brass products
Versatile, environmentally friendly and durable material, equally suitable for joining steel, polypropylene or copper pipes. Does not corrode. It works perfectly in hot water supply systems, heating, drinking water, gas and pneumatic pipelines. The disadvantages include the high cost and the impossibility of connection or repair by welding.
Stainless steel
They are cheaper than brass ones. They are more convenient when repairing pipelines, as they can be welded to the pipeline or welded holes and cracks. Heavy. In terms of the number of models, they are significantly inferior to brass ones, and the cost is slightly less.
Polypropylene
They are lightweight and affordable. The disadvantage is the ability to operate only with polypropylene pipes.
All of these materials are used for the manufacture of both industrial and household models.
Bandwidth
An important characteristic. Distinguish between full bore and partial bore models. The first ones are called so because the diameter of the ball hole coincides with the diameter of the pipeline, and their capacity is 100%. This also includes gates with a throughput characteristic in the range from 90 to 99%.
Partial bores are called:
- semi-bore, the diameter of the hole of which is one size smaller than the diameter of the pipe, and the throughput varies from 70 to 90%;
- partial bore - used to reduce water consumption, since they pass from 40 to 70% of the total flow.
By way of joining
This parameter is distinguished:
- Welded models. They are connected to pipelines by electric welding. It is secure and sealed. However, it is difficult to remove for replacement. We'll have to cut the pipe.This method is used in the construction of industrial facilities where all other methods are unprofitable or impossible for safety reasons.
- Flanged. They are produced with inlet and outlet flanges and are connected to the counter flanges on the pipeline. Typically used when laying pipelines with a diameter of two inches or more. The connection is simple and sufficiently tight. If necessary, it can be quickly disassembled and assembled.
- Wafer. Like the previous version, it is mounted to the counter flanges. The difference is that the product itself does not have flanges, but is simply installed between the pipeline flanges and tightened with bolts or studs. There is a so-called. hairpin models. They are fastened with bolts that are inserted into the holes of the pipeline flanges and screwed into the holes with an internal thread in the body of the structure.
- Coupling. They are joined on the thread. The advantages include ease of installation and dismantling. Suitable for use on pipelines with a diameter of two inches or less. Often used in household utilities. There is only one drawback, the lack of professionalism of the installer when sealing the connection will certainly lead to the formation of a leak.
- Combined option. Combinations of the listed options: inlet flange and outlet threads, or threads on one side and welded end on the other.
The method of connecting the reinforcement is determined at the stage of project development. In this case, the decision on one or another method of installation of valves is made taking into account the diameter and material of the pipeline.

This is not a complete list of brands whose products can be purchased with your eyes closed. It is up to you which company to buy the goods. In any case, you should listen to the advice of specialists in the installation of equipment, get the recommendations of consultants in a specialized store, study the description of the product, its characteristics, clarify how much the selected model costs and make the right choice.
How to choose a ball valve
To purchase a suitable model, you should understand some of the criteria for choosing shut-off valves:
- The diameter of the control elements of engineering networks must correspond to the diameter of the pipeline. On the side surface, the parameter is necessarily indicated in inches, for example, Dn1 ", or millimeters (25 mm).
- When choosing shut-off valves, check the pressure of the working medium in the pipeline and choose a valve with a "margin" of pressure. The value of the parameter in bars is applied to the surface of the product after the designation, for example, Pn 16 bar.
- Brass products have the greatest work resource. Samples made of stainless steel are cheaper, but they have a greater weight.
- For underground or underwater communications, it is better to choose welded models.
- When installing a drinking water supply system from polypropylene pipes, only plastic taps are used.
- Heating pipelines with high pressure of steam or water and with a diameter of 50 mm and more are better equipped with flange fittings.
What else to pay attention to
- Silumin shut-off valves are distinguished by a modest price and increased fragility. Buying a silumin crane is a waste of money.
- When installing the pipeline close to the wall, you should select shut-off valves with a butterfly handle. Unlike a long lever, it will not hit the wall and will not interfere with device control.
- If it is necessary to control the pressure of the pipeline using an indicating manometer, two or three-way ball valves are used, which make it possible to increase the life of the manometer, since the medium pressure is supplied to the device only when it is necessary to make the next observation.
- Before paying for the purchase, open and close the shutter several times, check how easy the apple walks. The tight movement of the shut-off element complicates the normal operation of the device.
- Better to choose an option. It has an extended set of functions: a built-in filter, a pile with a built-in thermometer or a drainage pipe for draining water in the winter (if it is a watering tap).
- For watering the garden, it is better to choose a corner hose tap. A special nozzle - a ruff, allows you to easily attach a rubber-fabric or plastic sleeve to the nozzle and secure it with a clamp. The same option will be ideal when tying a washing machine.
Where can I buy
It is best to do this in a specialized store. There is an opportunity to see and touch the product with your own hands and talk to a sales assistant. If this is not possible, you can order the product online in the online store.

Buying a ball valve can seem like a daunting task, even for an uninformed buyer. As a result, the purchased device may become covered with cracks along the body or stop hermetically blocking the flow a week after the start of operation. This happens when the buyer chased after cheapness and ran into a cheap Chinese fake. It may also happen that the buyer "dumps" a lot of money for a branded device, when it was possible to purchase an equally reliable option and pay a third less.
We hope that we managed to acquaint a potential buyer with the best manufacturers of such devices and highlight all the questions that arise when buying ball valves with manual or automatic control, so as not to make mistakes when choosing.
