J41H-16C傘齒輪傳動截止閥
法蘭連接的截止閥適用于公稱壓力PN1.6～6.4MPa,工作溫度-29～550℃的石油、化工、制藥、化肥、電力行業等各種工況的管路上，切斷或接通管路介質。適用介質為：水、油品、蒸氣、酸性介質等。操作方式有：手動、齒輪傳動、電動、氣動等。結構優勢與特點
產品設計制造按國家標準GB12235，結構合理，密封可靠，性能優良，造型美觀。
閥瓣、閥座密封面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。
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。
可采用各種配管法蘭標準及法蘭密封面形式，滿足各種工程需要和用戶要求。
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，填料與日俱更換可在不停機情況下進行方便快捷不影響系統運行。
