Cold flange valve advantages and disadvantages of cold flange valve advantages: 1, the fluid resistance. 2, external force required for opening and closing smaller. 3, the flow of medium is not limited. 4, fully open, the sealing surface by the erosion of the working medium smaller than the stop valve. 5, the shape is relatively simple, casting technology is better. Low temperature flange valve defects: 1, the overall dimensions and the opening height are large. Installation requires more space. 2, the process of opening and closing, there are relative friction between the sealing surface, easily lead to abrasions. 3, low-temperature flange valve two sealing surface, to the processing, grinding and maintenance to increase some difficulties.
