一、J41H法蘭截止閥主要用途:
法蘭截止閥,不銹鋼法蘭截止閥,J41H鑄鋼截止閥適用于公稱壓力PN1.6~16MPa,工作溫度0~425℃的石油、化工、制藥、化肥、電力行業等工況的管路上,切斷或接通管路介質。驅動方式有手動、齒輪傳動、電動、氣動等。J41H鑄鋼法蘭截止閥的啟閉件是圓柱形的閥瓣,密封面呈平面或錐面,閥瓣沿流體的中心線作直線運動。國標截止閥只適用于全開和全關,一般不用來調節流量,定做時允許作調節和節流。型號: J41H-16C(鑄鋼)、J41H-16P(304)、J41H-16R(316)、J41H-25C、J41H-40C、J41H-64C、J41H-64P、J41H-64R
二、J41H鑄鋼法蘭截止閥產品特點:
1、結構簡單,制造和維修比較方便
2、工作行程小,啟閉時間短
3、密封性好,密封面間磨擦力小,較長
