Stainless steel valves are widely used in chemical, petrochemical, petroleum, paper, mining, electric power, liquefied petroleum gas, food, pharmaceutical, water supply and drainage, municipal, mechanical equipment, electronics industry, urban construction and other fields. The 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 valves used in extremely complex automatic control systems, come in a wide variety of sizes and sizes. 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 valves can be from 0.13MPa to 1000MPa. The temperature ranges from an ultra-low temperature of -269 ° C to a high temperature of 1430 ° C.
Main features of stainless steel plug valves
1. The cross section of the gate is equal to the channel width; the ultra-wide type can be made into double lifting points to open and close.
2, adaptability to the depth of the channel;
3, rubber seal, good water stopping performance;
4, stainless steel production, good corrosion resistance;
Main features of stainless steel ball valves
1. The fluid resistance is small, and the drag coefficient is equal to the pipe length of the same length;
2. Simple structure, small size and light weight;
3. It is close and reliable. The sealing surface material of the current ball valve is widely used in plastic and has good sealing performance. It has also been widely used in vacuum systems.
4, easy to operate, open and close quickly, from full open to full off as long as rotated 90 °, easy to control over long distances;
5, the maintenance is convenient, the ball valve structure is simple, the sealing ring is generally active, and it is convenient to disassemble and replace;
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and when the medium passes, it will not cause erosion of the sealing surface of the valve;
7, stainless steel ball valve has a wide range of applications, from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied.
