Characteristics of American Standard Gate Valve

Writer:condiDate:2017-3-13 10:48
American standard gate valve for ANSI Class150 ~ 2500, PN20 ~ 42, JIS10 ~ 20K, operating temperature -29 ~ 425 ℃ (carbon steel) and -40 ~ 500 ℃ (stainless steel) on the line, for truncation or The medium in the pipe. Through the use of different materials, can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing media and urea and other media.
Features
① product design and manufacturing in line with foreign advanced standards, sealed and reliable, excellent performance.
② compact and reasonable structure design, handsome in appearance.
③ the use of wedge-shaped elastic gate structure, large diameter set of rolling bearings, open and close easily.
④ full range of valve body material, packing, gasket according to the actual conditions or user requirements reasonable matching, applicable to a variety of pressure, temperature and media conditions.
⑤ domestic and foreign use of a variety of piping flange and flange sealing surface type to meet the needs of various projects and user requirements.
