J641H氣動截止閥
一、主要用途
? J641H氣動截止閥采用雙作用氣缸，利用上腔進氣或者下腔進氣來遠距離控制閥門，操作方便、靈活。氣缸使用介質：壓縮空氣，氮氣。結構簡單、制造和維護方便；工作行程小，啟閉時間短；關閉體（閥瓣）與閥座密封面采用錐面密封，關閉力小，耐沖刷，密封可靠。閥座可為更換式閥座，可任意組合與關閉件密封面材料的配對，以滿足工況要求，延長使用壽命。
二、結構特點
?? 1、選材考究，符合國內、外相關標準，結構合理，造型美觀。
?? 2、閥瓣、閥座密封面采用鐵基合金堆焊或司太立（Stellite）鈷基硬質合金堆焊而成，耐磨、耐高溫、耐腐蝕、抗擦傷性能好，使用壽命長。
?? 3、閥桿經調質及表面氮化處理，有良好的抗腐蝕性和抗擦傷性。
?? 4、可采用各種配管法蘭標準及法蘭密封面型式，滿足各種工程需要及用戶要求。
?? 5、閥體材料品種齊全，填料、墊片可根據實際工況或用戶要求合理選配，能適用于各種壓力、溫度及介質工況。
?? 6、倒密封采用螺紋連接密封座或本體堆焊奧氏體不銹鋼而成，密封可靠，更換填料可在不停機情況下進行，方便快捷，不影響系統運行。
