{"id":776,"count":5,"description":"Brass ball valves are used in water supply systems, heating, and in the industrial segment. They are reliable, durable, easy to use and repair, and inexpensive. If you need to buy a brass ball valve, in the Ukspar online store you will definitely find the option of the desired configuration at a reasonable price with delivery across Ukraine.\r\n

Brass ball valves for water, heating and gas<\/span><\/h2>\r\nA brass ball valve is a type of shut-off valve used to completely shut off the flow of the working medium in pipeline systems. <\/span>Brass ball valves are widely used in water supply, heating, gas pipelines and industrial piping systems due to their high tightness, reliability and ease of operation.<\/span> Indispensable when you need to quickly and reliably cut off the flow of liquid, steam or gas in an emergency or for repairs.<\/span>\r\n\r\nBall valves can withstand pressures up to PN 140 and temperatures up to 250\u00b0C<\/span>, which allows them to be used in various systems where complete tightness and operational flow control are important. These include, in particular, cold and hot water supply systems, gas supply, central heating, pipelines in the gas, oil refining, chemical, and food industries.<\/span>\r\n

Structure and working principle of brass ball valve<\/span><\/h2>\r\nA brass ball valve consists of the following elements:<\/span>\r\n
    \r\n \t
  1. Housing. Has two holes for connection to the pipeline.<\/span><\/li>\r\n \t
  2. Ball (closing element). The main working part of the valve.<\/span> It has a through hole through which liquid can pass freely when the unit is in the open position.<\/span><\/li>\r\n \t
  3. Stem. The rod that connects the faucet handle and the ball. When the handle is turned, the stem transmits rotational motion to the ball.<\/span><\/li>\r\n \t
  4. Seals. Elements that ensure the tightness of the structure and prevent leaks of the working medium<\/span>.<\/span><\/li>\r\n \t
  5. Handle. A lever for operating a faucet. By turning it 90 degrees, you can open or close it.<\/span><\/li>\r\n<\/ol>\r\nThe principle by which brass valves work <\/span>ball valves<\/span><\/a>, is based on the rotation of a spherical locking element inside the body. When the tap handle (valve) is turned along the axis of the pipe, the hole in the ball coincides with the direction of flow of liquid or gas in the pipeline. In this position, the substance moves freely along the pipe and passes through the tap without loss of pressure. When the valve is located perpendicular to the axis of the pipe, the position of the hole in the ball changes and an obstacle is created that does not allow the liquid or gas to move further.<\/span>\r\n\r\nBrass ball valves provide minimal hydraulic resistance, quick flow shut-off, and reliable operation even under heavy use.<\/span>\r\n

    Types of brass ball valves<\/span><\/h2>\r\nBrass ball valves are among the most popular types of shut-off valves for domestic and industrial piping systems.<\/span>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

    Connection method<\/td>\r\nCoupling (threaded)<\/td>\r\nHas an external or internal thread for connection to the pipe.

    <\/td>\r\nFlanged<\/td>\r\nThe base has flanges at the ends for bolted connection to the pipeline. It is used together with large diameter pipe fittings in high pressure systems.<\/td>\r\nIndustrial installations, main pipelines.<\/td>\r\n<\/tr>\r\n
    <\/td>\r\nWelded<\/td>\r\nConnects to the pipe by welding.<\/td>\r\nSystems where it is important to ensure complete tightness and reliable protection against leaks (gas pipelines, chemical industry, etc.).<\/td>\r\n<\/tr>\r\n

    <\/td>\r\nPartially permeable (reduced) <\/span><\/td>\r\nThe diameter of the hole in the ball is smaller than the diameter of the pipe.<\/td>\r\nDomestic systems where a small pressure loss is not critical (connection to plumbing fixtures).<\/td>\r\n<\/tr>\r\n
