packing material<\/strong><\/h2><div>Valves are both mechanically and thermally stressed parts. Suffice it to say that in a 4-stroke engine, which runs at 5,000 rpm, a valve opens and closes more than 40 times per second.\u00a0<br \/>Added to this, in the case of the exhaust valve, is the thermal stress due to the flow of burnt gases that come out of the engine and wrap around the valve head. This is also the reason why intake and exhaust valves are built with very different materials.\u00a0<br \/>The former, in fact, undergo lower thermal stresses because they are hit by the fresh mixture. For this reason they are built with a single type of steel. To improve reliability, various stratagems can be used, such as surface hardening the rod with chrome coatings; this type of treatment also involves a benefit in terms of friction and greater resistance to corrosive agents.\u00a0<br \/>A further treatment that the valves can be subjected to is nitriding with which the wear resistance is improved and the fatigue limit of stainless and alloy steels is raised. Finally, the valve seat, subjected to corrosion and wear, is reinforced with stellite inserts.The inlet valves are usually made with medium alloy steels if intended for normal use. For the most stressed ones, chromium-silicon steels are used.\u00a0<br \/>The exhaust ones, on the other hand, are more stressed (the valve head can even exceed 800 \u00b0 C). For this reason they are made with special steels. In the case of low-stressed motors, chromium-silicon or nickel-chromium steels are used. In the case of engines subjected to heavier uses, chromium-nickel-manganese valves resistant to high temperatures can be found. For even more extreme ones, chromium-nickel steels are used with the addition of nitrogen which increases their mechanical characteristics. The valves made in this way have exceptional resistance to heat and corrosion.<\/div><h3>Materials for making valve parts are selected based on the following factors:<span style=\"mso-spacerun: 'yes'; font-size: 11.04pt; font-family: Calibri-Bold; color: #101218; font-weight: bold;\"><br \/><\/span><\/h3><div>1.

Requirements The gasket material has a certain elasticity, plasticity and strength sufficient at the operating temperature to ensure the seal. At the same time, it must have good corrosion resistance.<\/div><div>2. Types and material selection of seals Seals can be divided into soft and hard materials. Soft materials are generally non-metallic materials, such as cardboard, rubber, asbestos rubber sheets, PTFE and so on. Hard materials are usually metallic materials or asbestos coated with tangled metal, metal and asbestos, etc. There are many shapes of gaskets, including flat, round, oval, toothed, lens shaped and other special shapes. Metal gasket materials are generally high quality 08, 10, 20 carbon steel and 1Cr13, 1Cr18Ni9<\/div><div>stainless steel, which require high machining accuracy and surface finish and are suitable for high temperature and high pressure valves. Non-metallic gasket materials generally have good plasticity and can achieve sealing with little pressure. Suitable for low temperature and low pressure valves.

Plant-based fillers\u00a0 are cheaper and are often used for low pressure valves below 100 \u00b0 C; mineral fillers can be\u00a0 used for valves below 450 \u00b0 C. The packing on the high temperature and high pressure valve\u00a0 is also made of non-asbestos wool and flake graphite powder.<\/div><div><span style=\"mso-spacerun: 'yes'; font-size: 11.04pt; font-family: Wingdings; color: #000000;\">\uf0d8 <\/span><strong>Rigid packing <\/strong><\/div><div>That is, it is a metal or metal filler mixed with asbestos and graphite, and is composed of a formed filler that is pressed and sintered from polytetrafluoroethylene. Metal fillers use fewer fillers and should be selected based on medium, temperature and pressure.<\/div><div>Commonly used materials are the following:<\/div><div>1. Oil impregnated asbestos rope, suitable for valves with steam temperature of 450 \u2103 and nominal pressure lower than PN63.2. Asbestos rubber cable, suitable for valves with steam temperature of 450 \u2103 and nominal<\/div><div>pressure lower than PN63.<\/div><div>3. Graphite asbestos rope. The asbestos rope is infiltrated with graphite powder. It can be used at temperatures above 450 \u00b0 C. The nominal pressure can reach PN160. It is generally used on high pressure steam.<\/div><div>4. Polytetrafluoroethylene, which is a widely used filler, especially for corrosive fluids. The temperature should not exceed 200 \u2103 and is generally obtained by pressing or turning the bar.<\/div><div>5. Corrugated packaging is composed of concentric multi-layered metallic corrugated sheets forming a square section, which is pressed and formed in a mold. Each wave valve is filled with asbestos threads spun from asbestos fibers and the outer surface of the packing ring is covered<\/div><div>with scaly graphite. The corrugated filler sheet can be composed of stainless steel, copper and lead, which are suitable for any temperature level below 600 \u00b0 C, and are currently recommended as a new type of filler.<\/div><div>6. Flexible graphite is made from natural graphite through a special chemical treatment and heat treatment. Maintains the good corrosion resistance, high temperature resistance, high pressure resistance, radiation resistance, excellent thermal conductivity and electrical conductivity of natural graphite. The operating temperature range of flexible graphite is: -200 \u2103 ~ 1600 \u2103 in a non-oxidizing medium; -200 \u2103 700 \u2103 in an oxidizing medium (general working conditions); less than or equal to 700 \u2103 in a strong oxidizing medium Flexible graphite at 400 \u00b0 C has good corrosion resistance, but cannot be used in nitric acid with a concentration above 95%, sulfuric acid + nitric acid with a higher concentration to 96% and sulfuric acid with a concentration above 95%.<\/div><div>Valve Packaging Requirements:<\/div><div>1-Corrosion resistance<\/div><div>2-Good sealing performance<\/div><div>3-Low coefficient of friction\u00a0<\/div><\/div><div class=\"WB_editor_iframe_new\">\u00a0<\/div><\/div><\/div><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-toggle-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-1362\" class=\"elementor-tab-title\" data-tab=\"2\" role=\"button\" aria-controls=\"elementor-tab-content-1362\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon elementor-toggle-icon-right\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-closed\"><svg class=\"e-font-icon-svg e-fas-caret-right\" viewBox=\"0 0 192 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M0 384.662V127.338c0-17.818 21.543-26.741 34.142-14.142l128.662 128.662c7.81 7.81 7.81 20.474 0 28.284L34.142 398.804C21.543 411.404 0 402.48 0 384.662z\"><\/path><\/svg><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-opened\"><svg class=\"elementor-toggle-icon-opened e-font-icon-svg e-fas-caret-up\" viewBox=\"0 0 320 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M288.662 352H31.338c-17.818 0-26.741-21.543-14.142-34.142l128.662-128.662c7.81-7.81 20.474-7.81 28.284 0l128.662 128.662c12.6 12.599 3.676 34.142-14.142 34.142z\"><\/path><\/svg><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-toggle-title\" tabindex=\"0\">Which is better graphite or Teflon packing?<\/a>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t<div id=\"elementor-tab-content-1362\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"2\" role=\"region\" aria-labelledby=\"elementor-tab-title-1362\"><div><strong>Graphite VS Teflon (polytetrafluoroethylene) gasket: comparison<\/strong><\/div><div><strong>Graphite packing<\/strong> = made of flexible graphite wire as raw material.

aria-labelledby=\"elementor-tab-title-1365\"><p>The specific device of the packing test consists of a packing seal test bench and a test part for the characteristics of the packing wood body. The packing seal test bench is used to simulate a valve that uses packing as the valve stem seal, and has the function of detecting leakage at the valve packing. During the test, the valve stem is in a horizontal position. Considering the different orientation of the valve stem when the valve is actually used, it is considered that the position of the valve stem can be changed at any time during the test process, which will not interfere with the test results of the valve. In addition, the test device shall be equipped with a driving device to simulate the lifting or rotating movement of the valve stem, and the driving device shall ensure that no lateral loads and transverse stresses are applied to the valve stem. The unit shall be equipped with thermocouples and temperature monitors to ensure that the temperature stability of the stuffing box and fluid piping is provided and continuously monitored throughout the thermal cycle to avoid interfering with the results of the valve seal packing performance test. The device used for leak measurement shall be a certified ionizing flame steam analyzer to effectively collect and record the data obtained from the test.<\/p><p><br \/>The filler material test is a measurement of filler weight loss, density, leachables analysis, and lubricant content. The sample filler tested should be randomly selected to effectively perform reliable testing of the product produced by the manufacturer. In order to avoid the influence of temperature changes during the test results, it is of great significance to ensure the continuous reasonable and stable temperature conditions throughout the test process. The filler weight loss test is tested separately for lamellar graphite (flexible graphite) and braided graphite depending on the contact environment and action, and the lubricant content test includes the measurement of the content of PTFE and wet lubricant. Special element or component testing requirements can be set according to the different requirements of different working conditions for the elements of filler components.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-toggle-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-1366\" class=\"elementor-tab-title\" data-tab=\"6\" role=\"button\" aria-controls=\"elementor-tab-content-1366\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon elementor-toggle-icon-right\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-closed\"><svg class=\"e-font-icon-svg e-fas-caret-right\" viewBox=\"0 0 192 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M0 384.662V127.338c0-17.818 21.543-26.741 34.142-14.142l128.662 128.662c7.81 7.81 7.81 20.474 0 28.284L34.142 398.804C21.543 411.404 0 402.48 0 384.662z\"><\/path><\/svg><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-opened\"><svg class=\"elementor-toggle-icon-opened e-font-icon-svg e-fas-caret-up\" viewBox=\"0 0 320 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M288.662 352H31.338c-17.818 0-26.741-21.543-14.142-34.142l128.662-128.662c7.81-7.81 20.474-7.81 28.284 0l128.662 128.662c12.6 12.599 3.676 34.142-14.142 34.142z\"><\/path><\/svg><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-toggle-title\" tabindex=\"0\">What material is the valve made of?<\/a>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t<div id=\"elementor-tab-content-1366\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"6\" role=\"region\" aria-labelledby=\"elementor-tab-title-1366\"><p><b style=\"font-style: inherit;\">Commonly used valve materials are:<\/b><\/p><p><b>cast iron<\/b><\/p><p>Cast iron is subdivided into four categories: gray cast iron, malleable cast iron, ductile iron, and nickel cast iron. This article mainly introduces the two main cast iron materials made by BAND valves: gray cast iron and ductile iron.<\/p><p>Gray cast iron is cast iron with flake graphite, because the fracture is dark gray when broken, so it is called gray cast iron. Gray cast iron is the most widely used cast iron, and its output accounts for more than 80% of the total output of cast iron. The casting performance, cutting performance and wear resistance of gray cast iron are very good. Its disadvantage is that its strength, plasticity and toughness are lower than other cast irons.<\/p><p>Grey cast iron is used as the material of <a href=\"https:\/\/raymonvalve.com\/butterfly-valves\/\"><u>butterfly valve<\/u><\/a>, which is usually suitable for weak acid and weak alkali media such as water and air, but not suitable for pipelines with perhydrochloric acid and nitric acid media.<\/p><p><b>Ductile iron<\/b> is a high-strength cast iron material with very high strength, toughness and wear resistance, and its comprehensive performance is close to that of steel. At present, the application range of ductile iron is second only to gray cast iron. We often say &#8220;replace steel with iron&#8221;, which refers to ductile iron.<\/p><p>Ductile iron is used as the material of the butterfly valve, which has certain corrosion resistance and performance is much higher than that of the butterfly valve made of gray cast iron. The applicable medium includes steam, general gas and oil.<\/p><p><b>The second category: cast steel<\/b><\/p><p>Cast steel is a cast iron alloy, which is a general term for iron-based alloys used to produce castings that do not undergo eutectic transformation during solidification. The advantages of cast steel are greater design flexibility and variability, increased overall structural strength and a wide range of weight variations. Using cast steel as the butterfly valve material, the performance is better than that of cast iron but not as good as stainless steel. Butterfly valve made of cast steel is suitable for steam, non-corrosive gas, oil, etc.<\/p><p><b>The third category: stainless steel<\/b><\/p><p>Stainless steel refers to steel that is resistant to weak corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt, also known as stainless acid-resistant steel. Generally, the butterfly valve made of stainless steel has the best performance and can be used in more severe working conditions. It is used in some ultra-high temperature, ultra-low temperature and strong acid-base corrosive medium pipelines.

It is mostly used in the manufacture of high pressure, oxygen conditions, small diameter or other small batch valves. Forgings are selected under high temperature, high pressure or low temperature or special media; castings are generally only suitable for medium and low pressure, and are mostly used in the mass production of standardized formed valves.<\/p><p>2) The difference between material A351 CF3M and A182 F316L: The material corresponding to the two standards is 316 stainless steel. CF3M stands for casting and is often used as a valve material. The corresponding forged steel code is A182 F316L.
