{"id":624,"count":10,"description":"Brass shut-off valves are a key element of modern engineering networks. Due to the unique properties of the alloy, these products ensure stable operation of water supply and heating systems. The main purpose of the valves is to completely block or regulate the flow of the working medium (water, coolant, steam). Brass valves are characterized by high corrosion resistance, the ability to operate in a wide temperature range (from <strong>-20 \u00b0C<\/strong> to <strong>+180 \u00b0C<\/strong>) and long service life.\r\n<h2><strong>Types of brass fittings in plumbing systems<\/strong><\/h2>\r\nVarious types of products are used to complete pipelines, each of which has its own purpose:\r\n<ul>\r\n \t<li><a href=\"\/en\/krany-kulovi-latunni\/\">Ball valves<\/a> \u2014 the most popular type of shut-off valve. The working element (ball) rotates on <strong>90\u00b0<\/strong>, providing quick flow shut-off. Available in coupling (threaded) versions, as well as in versions with an &quot;American&quot; (quick-release connection).<\/li>\r\n \t<li><strong>Valves (shutoff valves)<\/strong> \u2014 unlike taps, they are designed not only for shut-off, but also for precise regulation of fluid flow. Most often used in heating systems.<\/li>\r\n \t<li><strong>Gate valves<\/strong> \u2014 used mainly on main lines (diameter from <strong>DN 40\u201350<\/strong>) for reliable flow shut-off at high operating pressures.<\/li>\r\n \t<li><strong>Connecting elements (&quot;Americans&quot;)<\/strong> \u2014 straight and angled assemblies that allow for quick assembly\/disassembly of system sections and changing the direction of the pipeline.<\/li>\r\n<\/ul>\r\n<h2><strong>Purpose and key benefits<\/strong><\/h2>\r\nBrass fittings perform critical functions for system safety and efficiency:\r\n<ol>\r\n \t<li><strong>Hermetic cut-off<\/strong> \u2014 the ability to quickly isolate an area for repair or replacement of equipment.<\/li>\r\n \t<li><strong>Adjusting parameters<\/strong> \u2014 change in pressure and flow rate of the medium within the operating parameters <strong>PN<\/strong> (nominal pressure).<\/li>\r\n \t<li><strong>Equipment protection<\/strong> \u2014 preventing damage to pumps, boilers and meters by controlling flow.<\/li>\r\n \t<li><strong>High tightness<\/strong> \u2014 most products meet high tightness classes (class A), which eliminates leaks.<\/li>\r\n<\/ol>\r\n<strong>Advantages of brass:<\/strong>\r\n<ul>\r\n \t<li>Mechanical strength and resistance to water hammer.<\/li>\r\n \t<li>Thermal stability (no deformation when heated).<\/li>\r\n \t<li>Versatility for domestic and industrial sectors.<\/li>\r\n \t<li>Easy installation thanks to precise threading.<\/li>\r\n<\/ul>\r\n<h2><strong>Corrosion resistance and durability<\/strong><\/h2>\r\nThe high performance characteristics of brass devices are due to the chemical composition of the alloy:\r\n<ul>\r\n \t<li><strong>Oxidation protection:<\/strong> Brass does not rust. A protective oxide film forms on its surface, which allows the fittings to be used in contact with fresh and even sea water.<\/li>\r\n \t<li><strong>Resource:<\/strong> With proper selection and operation, the service life is <strong>10\u201320 years<\/strong> or to <strong>50,000 cycles<\/strong> \u00ab&quot;open-closed&quot;.<\/li>\r\n \t<li><strong>Stability:<\/strong> The material withstands vibration loads and does not lose its properties under the influence of aggressive impurities in the coolant.<\/li>\r\n<\/ul>\r\n<h2><strong>Installation and operating rules<\/strong><\/h2>\r\nTo ensure maximum service life, it is recommended to follow the installation technology and care rules:\r\n<ol>\r\n \t<li><strong>Professional installation:<\/strong> The process includes thread preparation, use of seals (fum tape or sealants), pressing the system and final tightness testing.<\/li>\r\n \t<li><strong>Operating mode:<\/strong> Ball valves should only be in their extreme positions - <strong>\u00ab&quot;fully open&quot;\u00bb<\/strong> or <strong>\u00ab&quot;completely closed&quot;\u00bb<\/strong>. Using them in an intermediate state leads to premature wear of the seals.<\/li>\r\n \t<li><strong>Prevention:<\/strong> It is recommended to turn the handle every 6 months to prevent jamming due to salt and scale deposits.<\/li>\r\n<\/ol>\r\n<h3><strong>How to choose quality brass fittings?<\/strong><\/h3>\r\nWhen buying, pay attention to the following criteria:\r\n<ul>\r\n \t<li><strong>Product weight:<\/strong> A quality brass faucet cannot be too light (this is a sign of thin walls or the use of silumin).<\/li>\r\n \t<li><strong>Marking:<\/strong> Check the settings <strong>DN<\/strong> (notional diameter) and <strong>PN<\/strong> (working pressure).<\/li>\r\n \t<li><strong>Coating quality:<\/strong> The surface must be smooth, without cracks or swelling.<\/li>\r\n<\/ul>\r\nYou can buy certified brass fittings at a favorable price from the company <strong>UKSPAR<\/strong>.
