Stainless steel valves are commonly used in applications where the working medium is corrosive. The range of materials that can resist corrosion from such media is limited and often influenced by multiple factors. If the manufacturing process, including processing technology and heat treatment, is properly executed, the material’s corrosion resistance can be effectively ensured. However, for concentrated nitric acid with a concentration exceeding 98%, no heat treatment method can provide sufficient corrosion resistance. Therefore, when selecting valve materials based on the nature of the working medium, it's crucial to consider the effects of the medium’s concentration, temperature, and the material’s heat treatment process on its performance. Stainless steel valves have become essential in various industries due to their durability and resistance to corrosion. However, in China, very few manufacturers meet international quality standards. As a result, customers should always request production and delivery certificates from suppliers before purchasing stainless steel valves to ensure product quality and reduce the risk of buying substandard items. Today, high-quality stainless steel and sanitary valves that meet international standards are mainly sourced from Japan, Germany, the United States, the United Kingdom, and top-tier cities like Shanghai. A stainless steel valve is a key component in pipeline fluid systems, designed to control the flow, direction, and passage area of the medium. It serves functions such as shut-off, regulation, throttling, diversion, check, and pressure relief. These valves come in a wide variety, ranging from simple shut-off valves to complex automated control systems. They are available in sizes from small instrument valves to large industrial valves with diameters up to 10 meters. Stainless steel valves are suitable for controlling various fluids, including water, steam, oil, gas, slurry, corrosive media, liquid metals, and even radioactive substances. Their operating pressure can range from as low as 0.0013MPa to over 1000MPa, and they can function at temperatures from as low as -269°C to as high as 1430°C. Valves can be operated manually, electrically, hydraulically, pneumatically, or through other mechanisms like worm gears, electromagnetic drives, or hydraulic systems. Some valves operate automatically based on pressure, temperature, or other signals, while others simply open or close without external input. The movement of the valve’s closing elements—whether lifting, sliding, rotating, or swinging—enables precise control over the flow path and ensures effective system operation. Hexagon slotted nut, that is, the groove is machined above the hexagon nut. It is used in conjunction with threaded Bolt with hole and cotter pin to prevent the relative rotation of bolt and nut. Hexagon slotted nut is generally used in vibration and impact situations. After the nut is fastened, it needs to be equipped with cotter pin hole and installed with cotter pin. Such as lifting equipment, artillery, press, die-casting machine, etc. Hexagon Slotted Nut,Hexagon Castle Nut,Hexagon Slotted Nut M10,Ss304 Hexagon Slotted Nut Jiangsu Jiajie Special Screw Co., Ltd , https://www.jiajiescrewcompany.com
