Where to use 1-2-1-2 angle tap

Water supply

Zatevaya repair in the bathroom, we, willy-nilly, have to deal with valves. The bathroom is just stuffed with various devices, ranging from a washing machine and ending with a heated towel rail. Each of them is required to bring water - to some cold (toilet bowl, washing machine), to others cold and hot (bath, shower, sink mixer), to the third only hot (heating radiator, heated towel rail). The most common use for this is ball corner valves.

Difference of the gas crane from exclusively water

Choosing the appropriate diameter of the fittings, you can stumble not only on the one that is used exclusively for water, but also for natural gas. Typically, the valve of such a crane is painted yellow, but this is not an indicator.

The gas angle valve 1 2 differs from an exceptionally water one by a more reliable oil seal:

  • if a rubber gasket is used, then lubrication will definitely be with it;
  • For fluoroplastic, the gland nut is always an addition.

In addition, such products in production are subjected to more stringent testing. Therefore, if you purchase a gas ball valve from a well-known brand, you can install it on water, oil products, and non-corrosive liquids as well.

Material

There are two types of cranes on the shelves of retail chains and markets:

Metallic
  1. Steel - the most reliable option for the supply of metal pipes to the desired plumbing fixture. Withstand high temperatures and can be used for steam heating. A steel angle valve with an American 1 2 allows you to quickly attach the pipeline and in a short time to disconnect it.
  2. Brass - the most common form, which is widely used for domestic purposes and in production. You can easily connect it to the equipment with your own hands. In the manufacture of these valves use two technologies:
    • forging;
    • casting.

    The first method is usually considered more reliable. This is due to the fact that during casting places with a non-uniform material structure are often formed. To prevent rust formation, as there are both zinc and lead in the composition of brass, a protective coating is applied by electroplating to the products. After that, they become mirror shiny, resembling stainless steel.
    Polymer Plastic taps as a type of stop valves appeared relatively recently, however, they have already managed to please consumers. Produce them from polypropylene or polyethylene, which allows structures not to be afraid of corrosion. In addition, the products are resistant to the transportation of aggressive substances. The price of a plastic tap is lower than metal counterparts. The downside is that fittings cannot be used for hot liquids whose temperature exceeds 95? C. In this case, they may begin to deform, causing loss of tightness.

    Advice: use brass faucets only for working medium with temperature up to 150? С. Otherwise, the process of "washing out" of the metal will begin, which will make the material porous.

    The principle of the ball valve

    Unlike the cone version, the ball is not designed to regulate the flow of fluid. With it, you can only open or block the passage of the pipeline completely. This must be remembered, otherwise it will be necessary for some time for the equipment to look for parts or completely change it.

    How does the ball valve

    The locking element in this case is a ball in which a hole is made in the middle. Turning the lever to the left and right, you simultaneously turn the ball around its axis, thereby opening the way for the passage of working fluid or is blocked. The locking element can be stationary on supports (for large diameters) or floating (as in our case).

    How not to be mistaken when choosing a product

    Any valves and fittings, first of all, is a guarantee that in your absence nothing will happen to the water supply system and heating. Therefore, before you buy a product, you should find out about the warranty provided by the manufacturer.

    Alas, today stumble on a fake can be everywhere - in the construction market, and in the trading network.

    Tip: do not be lazy and ask the seller to see the manufacturer's warranty on the crane. You must provide a passport for the selected product.

    1. One of the easiest ways to check a crane for quality is to use a magnet.. If it sticks to it, it means that there is a lot of iron in this product, so it’s better not to buy it. But today fraudsters have learned how to make water taps out of zinc, so the above method, alas, cannot always help.
    2. Look carefully at the markings on the product.. There is always something missing on a fake - for example, the working pressure, the stamp of the manufacturer or the exact size.

    1. Weigh the selected tap in your hand, it should not be incredibly light, brass, in itself, heavy.
    2. The instruction recommends that for our conditions, when the temperature of the coolant is higher than, say, in Europe, only heat-resistant teflon is used in the construction of the crane..

    Conclusion

    Thanks to the angular ball valve, it became possible to accurately connect various appliances to the pipelines, for example, radiators and heated towel rails. Products are made from different materials, including steel, brass with electroplated coating and polymers. When choosing, it is necessary to take into account the temperature of the working fluid, as well as to which pipeline the valves are connected.

    Do not forget also that the ball valve should work only in two positions - open and closed, they can not regulate the flow. The video in this article will provide an opportunity to find additional information on the above topic.
