Stainless steel valves are typically used where the working medium is corrosive. Any valve material that is resistant to corrosion by working media is relatively limited and subject to many factors. If the processing technology and heat treatment process used in the manufacturing process are proper, the corrosion resistance of the material is ensured.
As for the concentrated nitric acid medium with a concentration of >98%, no matter what kind of heat treatment process is used, the steel has no corrosion resistance. Therefore, when selecting the valve material according to the nature of the working medium, it is necessary to study the influence of the concentration of the medium, the temperature and the heat treatment process of the material on the corrosion resistance.
Stainless steel valves have become a must-have valve product in various industries. However, there are very few valve manufacturers that can meet international standards in China. Therefore, customers must require merchants to provide various stainless steel valve production and delivery certificates before purchasing stainless steel valves. Can reduce the purchase of unqualified products. Today, stainless steel valves and sanitary valves meet the international standards of valves mainly from Japan, Germany, the United States, the United Kingdom and the first-tier cities in Shanghai.
The stainless steel valve is a control component in the pipeline fluid delivery system. It is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cutoff, regulation, throttling, check, diversion or overflow relief. Valves for fluid control, from the simplest shut-off valves to the most complex self-control systems, are available in a wide variety of sizes and sizes. The nominal diameter of the valve ranges from very small instrument valves up to 10m. Valves for industrial piping.
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 metal and radioactive fluid. The working pressure of the valve can be from 0.0013MPa to 1000MPa. From ultra-low temperature of -269 ° C to high temperature of 1430 ° C. The valve can be controlled by various transmission methods, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic motion, electromagnetic-hydraulic, electro-hydraulic, gas-hydraulic, spur gear, bevel gear drive, etc. It can be operated under the action of pressure, temperature or other forms of sensing signals, according to predetermined requirements, or simply turned on or off without relying on the sensing signal. The valve relies on the drive or automatic mechanism to make the opening and closing parts lift and slide. Move, swivel or swivel motion to change the size of its runner area to achieve its control function.
