First introduction: classification of stainless steel valves
 
Stainless steel valves can be divided into the following types according to their uses:   
 
1. Stainless steel butterfly valve: such as stainless steel manual butterfly valve, stainless steel electric butterfly valve, stainless steel pneumatic butterfly valve
2. Stainless steel ball valve: such as stainless steel pneumatic ball valve, stainless steel ball valve, stainless steel flange ball valve, stainless steel four-way ball valve, stainless steel card sleeve ball valve, stainless steel heat preservation ball valve
3. Stainless steel gate valve: such as stainless steel gate valve, stainless steel flange gate valve, stainless steel insulation gate valve, stainless steel high pressure gate valve
4. Stainless steel check valve: for example, stainless steel check valve, swing check valve, stainless steel lift check valve, stainless steel wafer check valve, stainless steel swing check valve
5. Stainless steel globe valve: such as stainless steel bevel gear globe valve, stainless steel hydraulic globe valve, stainless steel external thread globe valve, stainless steel internal thread globe valve, stainless steel flange globe valve
 
Overview of stainless steel valves: As the name suggests, stainless steel valves are valves made of stainless steel.
Stainless steel valves have successively enhanced material quality, generally 304 stainless steel, 304L stainless steel, 316 stainless steel, 316L stainless steel and two-way stainless steel.
Stainless steel valves use industries: food biscuit industry, instant noodles and rice noodles industry, various quick-frozen food dehydration line equipment, glass products industry. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.
Stainless steel valves are widely used in chemical, petrochemical, petroleum, papermaking, mining, electric power, liquefied gas, food, pharmaceuticals, water supply and drainage, municipal administration, mechanical equipment, electronics industry, urban construction and other fields.
 
The stainless steel valve is a control component in the pipeline fluid conveying system. It is used to change the passage section and the flow direction of the medium. It has the functions of diversion, cutoff, adjustment, throttling, check, diversion or overflow pressure relief. Valves used for fluid control, from simple shut-off valves to various valves used in complex automatic control systems, have a wide range of varieties and specifications. Stainless steel valves 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 working pressure of the valve can be from 0.0013MPa to 1000MPa high pressure and working temperature From the ultra-low temperature of -269℃ to the high temperature of 1430℃.
 
Stainless steel valves are usually used where the working medium is corrosive. Any kind of valve material has relatively limited resistance to corrosion by the working medium and is affected by many factors. If the processing technology and heat treatment technology used in the manufacturing process are proper, the corrosion resistance of this material can be guaranteed. As for the concentrated nitric acid medium with a concentration of >98%, no matter what heat treatment process is used, this steel does not have corrosion resistance. Therefore, when selecting the valve material according to the nature of the working medium, the influence of various factors such as the concentration of the medium, the temperature and the heat treatment process of the material on the corrosion resistance is studied at the same time. Stainless steel valves have become a must-purchased valve product in various industries. However, there are very few domestic valve manufacturers that can meet international standards. Therefore, customers must request manufacturers to provide various stainless steel valve production and factory certifications before purchasing stainless steel valves. Can reduce the purchase of substandard products. Nowadays, stainless steel valves and sanitary valves that meet international standards are mainly from Japan, Germany, the United States, the United Kingdom and the domestic first-tier city Shanghai. Stainless steel valve Valve is a control component in the pipeline fluid conveying system. It is used to change the passage section and the flow direction of the medium. It has the functions of diversion, cut-off, adjustment, throttling, check, diversion or overflow pressure relief. Valves used for fluid control, from simple shut-off valves to various valves used in complex automatic control systems, have a wide range of varieties and specifications. Valves can be used to control water, steam, oil, gas, mud, and various corrosive media. The valve can be controlled by 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. ; Under the action of pressure, temperature or other forms of sensing signals, it can act according to the predetermined requirements, or simply open or close without relying on the sensing signals. The valve relies on the drive or automatic mechanism to make the opening and closing parts lift and slide Move, swing or rotate to change the size of the flow channel area to achieve its control function.
