The difference between stainless steel ball valve and butterfly valve

Stainless steel ball valve and RiFeng butterfly valve are both commonly used valves, with wide application range The big difference between them lies in the valve structure and working characteristics The main characteristics of stainless steel ball valve are: 1 Small flow resistance; 2 Stainless steel flange ball valve can achieve complete sealing under large pressure and high temperature; 3 Cast steel ball valve can be opened and closed quickly; 4 The cast steel flange ball valve has high corrosion resistance; 5 The valve body is symmetrical, which can effectively bear the pipeline pressure, and can cope with various high-pressure vacuum conditions, with a wide range of applications; the opening and closing parts of Shanghai Hongfeng butterfly valve are disc left and right opening, with the main characteristics of: 1 Simple structure, small volume, easy installation; 2 Small flow resistance coefficient, fast opening and closing,; 3 It can be used for large-diameter valves; 4 It can be used for different sealing surfaces and various environments, including powder and granular media Relatively speaking, the tightness of ball valve is better The two have their own advantages relatively With the progress of the times and the development of science and technology, the ball valve is also changing with each passing day, and the technology is relatively mature There are more and more ball valve manufacturers with large caliber and stronger strength Compared with the butterfly valve, the ball valve has better sealing performance, easy maintenance, high pressure, wide application of sealing surface, and stronger development But the cost is relatively higher than the development of butterfly valve for a long time, and the technology is more perfect, relatively speaking, there are advantages and disadvantages.
