The working principle of 2520 ball valve is to rotate the valve stem to make the valve unobstructed or blocked. The 2520 ball valve switch is lightweight, small in size, and can be made into a large diameter. It has reliable sealing performance, simple structure, and convenient maintenance. The sealing surface and spherical surface are often in a closed state, and are not easily eroded by media. The 2520 valve produced by Oudian Valve is widely used in various industries.

3.2520 310s ball valve due to nickel NN (With high content of Cn, it has good oxidation resistance, corrosion resistance, acid resistance and high temperature resistance. High temperature resistant steel pipes are specially used for manufacturing electric furnace tubes and other occasions. After the carbon content is increased in austenitic stainless steel, its strength is improved due to its Solid solution strengthening effect. The chemical composition of austenitic stainless steel is characterized by adding elements such as silver, tungsten, silver and iron based on chromium and nickel. Because its structure is face centered cubic, it has a high temperature Strength and creep strength. 2520 stainless steel materials include 2520 stainless steel plate, 2520 stainless steel rod, and 2520 stainless steel pipe

4.310S 2520 stainless steel floating ball valve Material characteristics:

310S 2520 stainless steel floating ball valve material 310S  2520 stainless steel belongs to 25CR-20NI series of high-alloy stainless steel, high temperature oxidation resistance is excellent, suitable for making various furnace components, max. high temperature 1200℃, continuous use temperature 1150℃.  310S 2520 stainless steel floating ball valve is used for furnace, materials for automobile purification plant.310S stainless steel is austenitic chromium-nickel stainless steel with good oxidation resistance and corrosion resistance, because of the higher percentage of chromium and nickel, it has much better creep strength, can continue to work at high temperatures, has good high temperature resistance.Nickel (Ni), chromium (Cr) content is high, has good resistance to oxidation and corrosion resistance, acid and alkali resistance, high temperature performance, high temperature resistant steel pipe is dedicated to manufacturing occasions such as the electric heating furnace tubes, stainless steel after the increase of carbon content in austenite size, due to its solid solution strengthening effect strength was improved, the chemical composition of stainless steel austenite size features based on chromium, nickel, add, tungsten molybdenum, niobium and titanium elements, due to its organization is face-centered cubic structure, thus has high strength and creep at high temperature strength.
