Stainless steel valves are usually used where the working medium is corrosive. The ability of any valve material to resist the corrosion of working media is relatively limited and is influenced by many factors. If the processing and heat treatment processes used in the manufacturing process are appropriate, then the corrosion resistance of this material is guaranteed. As for the concentrated nitric acid medium with a concentration of >98%, the steel does not have corrosion resistance regardless of the heat treatment process. Therefore, when selecting the valve material according to the nature of the working medium, it is necessary to simultaneously study the influence of factors such as the concentration of the medium, the temperature, and the heat treatment process of the material on the corrosion resistance.
Stainless steel valves have become the must-procurement valve products in various industries. However, few domestic valve manufacturers have reached international standards. Therefore, customers must request manufacturers to provide various stainless steel valves before they purchase stainless steel valves. Can reduce the purchase of unqualified products. Today, stainless steel valves and sanitary valves have reached international standards, mainly from Japan, Germany, the United States, the United Kingdom, and domestic first-tier cities Shanghai.
Stainless steel valve The valve is the control component in the pipeline fluid delivery system. It is used to change the path section and the direction of the medium flow. It has functions such as diversion, cut-off, regulation, throttling, non-return, diversion, or pressure relief. Valves for fluid control, ranging from the simplest stop valve to various valves used in highly complex automatic control systems, are available in a wide range of sizes and sizes. The valve's nominal diameter ranges from extremely small gauge valves up to 10m in diameter. Industrial pipeline valves. The valve can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals, and radioactive fluids. The valve's working pressure can range from 0.0013 MPa to 1000 MPa ultra-high pressure, working temperature From -269 °C ultra-low temperature to 1430 °C high temperature. Valve control can use a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic, electromagnetic - hydraulic, electric - hydraulic, pneumatic - hydraulic, spur gear, bevel gear drive, etc. Can be under the action of pressure, temperature or other forms of sensing signal, according to the predetermined requirements, or do not rely on the sensor signal for simple opening or closing, the valve depends on the drive or automatic mechanism to make the opening and closing parts for lifting, sliding Move, swing, or swivel to change the size of the runner area to achieve its control function.
