Design

Consider what a ball valve and its device:

  1. The mechanism consists of a body and two pipe lengths through which the working medium passes.
  2. The material of this valve is often steel, but it can also be cast iron, brass, and combined options with polypropylene parts.
  3. The body has a ball with a hole inside, which may be the same as a section of a pipe or slightly smaller.

Now consider the device, called "American", to understand why it is needed. The peculiarity of the product is that it allows you to crash into the trunk without rotating the pipe.

This is achieved by including in the design on the valve cap nuts, with a fitting located under them with a gasket. In this connection, the adjustment is made through the use of special axial clamping, when only two large nuts are subject to rotation.

Crane ball with an American uses the principle of reciprocal rotation, leading to the fixed fastening all the other details of the design. It has a special plug-type connection, so when you dock with the pipe, you only need to tighten two locknuts, which is very convenient. This ensures the reliability and tightness of the connection due to the use of a cap nut, which has a gasket in the form of a washer inside.

In addition, this design minimizes the pressure reduction of the medium flowing through it, and this is also important.

Tip: it is recommended to install products of such a plan when installing sensors and counters for more accurate results.

Most experts consider the product one of the most reliable parts of valves. If you need to disconnect the radiator from the heating system without any extra effort, we recommend connecting the ball valves with an American from both sides. You can also adjust the pressure and water pressure in the system with your own hands, affecting the temperature of the heater and the heating in the room.

In addition to connecting radiators to the heating system, the products are used for installation:

  • boilers;
  • heated towel rails;
  • pumps;
  • boilers;
  • various filters.

Types of equipment

Before buying a product, it is necessary to understand its varieties, and what are these or other modifications intended for. Let us consider in more detail the classification of sanitary devices of this type:

In the direction of the pipeline
  1. Direct type of crane installed on a flat pipe.
  2. Corner - montage is made on the corner section corresponding to the angle of 90 ?.
A pen
  1. Butterfly - is used on products of small section, as for turning the valve it is required to use a small force.
  2. Lever - put on pipelines with a large cross section due to the application of a large force to turn the valve. The large length of the handle does not always allow you to conveniently use the sanitary device.
Rebar size
  1. The most common product in everyday life is considered to be O 1 inch or O 3/4.
  2. There are options and larger diameter - on 1 1 2 and 2.
Adjustment of this device is made by the handle lever

There are also several subspecies:

  1. Decorative - the same crane, only the original appearance, which can not be bought in every store, is often used for different design decisions.
  2. Special - made piece and for specific tasks, often for non-standard pipe diameter.
  3. With different thread, brand:
    • BB - internal from two sides;
    • NN - external on both sides;
    • NV - versatile (external on the one hand, internal on the other).

    Tip: the purchase of cranes of this modification provides ease of operation and eliminates the problems associated with rolling.

    The price of the product depends on the manufacturer and ranges from $ 3 (Neptun) to $ 10 (Bugatti). When choosing a device, its diameter and the diameter of the pipeline must be the same.

    Equipment installation stages

    The instructions for the installation of the product are simple, you only need to purchase a special key suitable for the "American".

    1. Check before installation the integrity of the thread on the pipe, if necessary, update it. Remove from the old thread the remnants of tape, gaskets and tow. Carefully clean the coils to perfect cleanliness.

    3. Check before installation - the adjusting knob must make a full turn, closing and opening the valve passage.
    4. Turn the valve on 4-5 turns.
    5. Make sure you tighten the nuts completely and turn on the water supply..
    Connecting a crane with an American to the radiator
    1. Observe the connection points for leaks for a few minutes..

    Tip: you notice a leak, or the water begins to dig through the nut, tighten it with a key.

    Conclusion

    Ball valve with an American allows you to get rid of the sanitary sgon, simplifies the connection of equipment to the pipeline. Installation work is simple and well done on its own. The video in this article will provide an opportunity to find additional information on the above topic.
